यदि \(2+\sqrt{3}\) किसी परिमेय गुणांक वाले बहुपद का शून्यक है, तो किस रैखिक गुणनखंड का साथ आना अपेक्षित है?

If \(2+\sqrt{3}\) is a zero of a polynomial with rational coefficients, which linear factor is expected to accompany it?

Explanation opens after your attempt
Correct Answer

A. (x-\(2-\sqrt{3}\))

Step 1

Concept

The companion zero is \(2-\sqrt{3}\), so the factor is (x-\(2-\sqrt{3}\)). In exams remember the relation between a zero and factor as \(x-\alpha\).

Step 2

Why this answer is correct

The correct answer is A. (x-\(2-\sqrt{3}\)). The companion zero is \(2-\sqrt{3}\), so the factor is (x-\(2-\sqrt{3}\)). In exams remember the relation between a zero and factor as \(x-\alpha\).

Step 3

Exam Tip

साथी शून्यक \(2-\sqrt{3}\) होगा, इसलिए गुणनखंड (x-\(2-\sqrt{3}\)) है। परीक्षा में शून्यक और गुणनखंड का संबंध \(x-\alpha\) याद रखें।

यदि (p(x)=2x-2-3x+\sqrt{2}), तो यह किस प्रकार का बहुपद है?

If (p(x)=2x-2-3x+\sqrt{2}), what type of polynomial is it?

Explanation opens after your attempt
Correct Answer

A. वास्तविक गुणांकों वाला द्विघात बहुपदQuadratic polynomial with real coefficients

Step 1

Concept

\(\sqrt{2}\) is real but irrational, so the coefficients are real but not all rational. Since the degree is (2), it is quadratic.

Step 2

Why this answer is correct

The correct answer is A. वास्तविक गुणांकों वाला द्विघात बहुपद / Quadratic polynomial with real coefficients. \(\sqrt{2}\) is real but irrational, so the coefficients are real but not all rational. Since the degree is (2), it is quadratic.

कौन सा कथन हमेशा सही है यदि द्विघात बहुपद के परिमेय गुणांक और एक शून्यक \(\sqrt{13}\) है?

Which statement is always true if a quadratic polynomial has rational coefficients and one zero is \(\sqrt{13}\)?

Explanation opens after your attempt
Correct Answer

A. दूसरा शून्यक \(-\sqrt{13}\) होगाThe other zero will be \(-\sqrt{13}\)

Step 1

Concept

For rational coefficients, the conjugate \(-\sqrt{13}\) of \(\sqrt{13}\) also appears when the linear coefficient is rational. This follows from \(a+\sqrt{b}\) and \(a-\sqrt{b}\).

Step 2

Why this answer is correct

The correct answer is A. दूसरा शून्यक \(-\sqrt{13}\) होगा / The other zero will be \(-\sqrt{13}\). For rational coefficients, the conjugate \(-\sqrt{13}\) of \(\sqrt{13}\) also appears when the linear coefficient is rational. This follows from \(a+\sqrt{b}\) and \(a-\sqrt{b}\).

Step 3

Exam Tip

यदि \(a+b\sqrt{2}=0\) है जहां (a) और (b) परिमेय हैं तथा \(b\neq 0\) है तो क्या निष्कर्ष निकलेगा?

If \(a+b\sqrt{2}=0\) where (a) and (b) are rational and \(b\neq 0\) then what conclusion follows?

Explanation opens after your attempt
Correct Answer

A. \(\sqrt{2}=-\frac{a}{b}\) परिमेय होगा जो असंभव है\(\sqrt{2}=-\frac{a}{b}\) would be rational which is impossible

Step 1

Concept

The equation gives \(\sqrt{2}=-\frac{a}{b}\).

Step 2

Why this answer is correct

\(-\frac{a}{b}\) is rational but \(\sqrt{2}\) is irrational.

Step 3

Exam Tip

Such questions use irrationality to create a contradiction. चरण 1: समीकरण से \(\sqrt{2}=-\frac{a}{b}\) मिलेगा। चरण 2: \(-\frac{a}{b}\) परिमेय है लेकिन \(\sqrt{2}\) अपरिमेय है। चरण 3: ऐसे प्रश्नों में अपरिमेयता से विरोधाभास बनता है।

Exam Tip

Always reduce the final remainder below the divisor. चरण 1: (p) का शेषफल 11 है। चरण 2: (4p-9) का शेषफल \(4\times11-9=35\) से मिलेगा, और \(35=13\times2+9\)। चरण 3: अंतिम शेषफल को हमेशा भाजक से कम करें।

Question Hard Mathematics Real Numbers 1: Euclid’s Division Lemma Class 10 Level 3

यदि (n) को 19 से भाग देने पर शेषफल 8 है, तो (5n+7) को 19 से भाग देने पर शेषफल क्या होगा?

If (n) leaves remainder 8 when divided by 19, what is the remainder when (5n+7) is divided by 19?

Explanation opens after your attempt
Correct Answer

A. 9

Step 1

Concept

Let (n=19q+8).

Step 2

Why this answer is correct

The remainder of (5n+7) comes from \(5\times8+7=47\), and \(47=19\times2+9\).

Step 3

Exam Tip

In a linear expression, using the remainder keeps the calculation short. चरण 1: (n=19q+8) मानें। चरण 2: (5n+7) का शेषफल \(5\times8+7=47\) से मिलेगा, और \(47=19\times2+9\)। चरण 3: रैखिक व्यंजक में शेषफल रखकर गणना छोटी हो जाती है।

Question Hard Mathematics Real Numbers 1: Euclid’s Division Lemma Class 10 Level 2

यदि (a) को 9 से भाग देने पर शेषफल 4 है और (b) को 9 से भाग देने पर शेषफल 7 है, तो (2a+b) को 9 से भाग देने पर शेषफल क्या होगा?

If (a) leaves remainder 4 when divided by 9 and (b) leaves remainder 7 when divided by 9, what is the remainder when (2a+b) is divided by 9?

Explanation opens after your attempt
Correct Answer

B. 6

Step 1

Concept

In (2a+b), the remainder part is \(2\times4+7=15\).

Step 2

Why this answer is correct

(15=9+6), so the remainder is 6.

Step 3

Exam Tip

In such questions, handle the remainder of each term separately. चरण 1: (2a+b) में शेषफल \(2\times4+7=15\) होगा। चरण 2: (15=9+6), इसलिए शेषफल 6 है। चरण 3: ऐसे प्रश्नों में प्रत्येक पद का शेषफल अलग संभालें।

यदि (t=16q+9), तो (2t+3) को 16 से भाग देने पर शेषफल क्या होगा?

If (t=16q+9), what is the remainder when (2t+3) is divided by 16?

Explanation opens after your attempt
Correct Answer

A. 5

Step 1

Concept

The remainder of (t) is 9.

Step 2

Why this answer is correct

The remainder part of (2t+3) is \(2\times9+3=21\), and (21=16+5).

Step 3

Exam Tip

Do not forget to reduce the final remainder below 16. चरण 1: (t) का शेषफल 9 है। चरण 2: (2t+3) का शेषफल \(2\times9+3=21\) होगा, और (21=16+5)। चरण 3: अंतिम शेषफल को 16 से कम करना न भूलें।

यदि (p=11q+8), तो (3p-7) को 11 से भाग देने पर शेषफल क्या होगा?

If (p=11q+8), what is the remainder when (3p-7) is divided by 11?

Explanation opens after your attempt
Correct Answer

B. 6

Step 1

Concept

The remainder of (p) is 8.

Step 2

Why this answer is correct

For (3p-7), the remainder part is \(3\times8-7=17\), and (17=11+6).

Step 3

Exam Tip

In a linear expression, always reduce the final remainder below the divisor. चरण 1: (p) का शेषफल 8 है। चरण 2: (3p-7) में शेषफल \(3\times8-7=17\) होगा, और (17=11+6)। चरण 3: रैखिक व्यंजक में अंतिम शेषफल हमेशा भाजक से छोटा करें।

यदि (n) को 17 से भाग देने पर शेषफल 6 है, तो (4n+5) को 17 से भाग देने पर शेषफल क्या होगा?

If (n) leaves remainder 6 when divided by 17, what is the remainder when (4n+5) is divided by 17?

Explanation opens after your attempt
Correct Answer

B. 12

Step 1

Concept

Let (n=17q+6).

Step 2

Why this answer is correct

(4n+5=68q+24+5=68q+29=17(4q+1)+12).

Step 3

Exam Tip

In a linear expression, first multiply the remainder and then reduce by the divisor. चरण 1: (n=17q+6) मानें। चरण 2: (4n+5=68q+24+5=68q+29=17(4q+1)+12)। चरण 3: रैखिक रूप में पहले शेषफल को गुणा करें और फिर भाजक से घटाएं।

यदि (y) को 9 से भाग देने पर शेषफल 2 है, तो (5y+4) को 9 से भाग देने पर शेषफल क्या होगा?

If (y) leaves remainder 2 when divided by 9, what is the remainder when (5y+4) is divided by 9?

Explanation opens after your attempt
Correct Answer

B. 5

Step 1

Concept

Let (y=9q+2).

Step 2

Why this answer is correct

(5y+4=45q+10+4=45q+14=9(5q+1)+5).

Step 3

Exam Tip

For a linear expression, replace the number by its remainder and simplify. चरण 1: (y=9q+2) मानें। चरण 2: (5y+4=45q+10+4=45q+14=9(5q+1)+5)। चरण 3: रैखिक रूप में पहले शेषफल रखें, फिर सरल करें।
