Question Medium Mathematics Chapter 1: Real Numbers 5: Irrational numbers Class 10 Level 14

यदि \(x=4+\sqrt{7}\), तो (x-4) कैसी संख्या है?

If \(x=4+\sqrt{7}\), what type of number is (x-4)?

Explanation opens after your attempt
Correct Answer

C. अपरिमेयIrrational

Step 1

Concept

(x-4=\(4+\sqrt{7}\)-4).

Step 2

Why this answer is correct

This leaves \(\sqrt{7}\), which is irrational.

Step 3

Exam Tip

First simplify the expression, then identify the nature of the number. चरण 1: (x-4=\(4+\sqrt{7}\)-4) होगा। चरण 2: इससे \(\sqrt{7}\) बचता है, जो अपरिमेय है। चरण 3: पहले अभिव्यक्ति को सरल करें, फिर संख्या की प्रकृति बताएं।

निम्नलिखित में से कौन-सा मान \(\sqrt{7}\) के सबसे निकट है?

Which of the following values is closest to \(\sqrt{7}\)?

Explanation opens after your attempt
Correct Answer

B. (2.65)

Step 1

Concept

Since (4<7<9), \(\sqrt{7}\) lies between (2) and (3).

Step 2

Why this answer is correct

\(\sqrt{7}\approx2.646\), so (2.65) is the closest.

Step 3

Exam Tip

In approximation, first set the range using perfect squares. चरण 1: (4<7<9), इसलिए \(\sqrt{7}\) (2) और (3) के बीच है। चरण 2: \(\sqrt{7}\approx2.646\), इसलिए (2.65) सबसे निकट है। चरण 3: अनुमान में पहले पूर्ण वर्गों से सीमा तय करें।

कौन-सी संख्या \(\sqrt{75}\) के बराबर है?

Which number is equal to \(\sqrt{75}\)?

Explanation opens after your attempt
Correct Answer

B. \(5\sqrt{3}\)

Step 1

Concept

\(75=25 \times 3\).

Step 2

Why this answer is correct

\(\sqrt{75}=5\sqrt{3}\).

Step 3

Exam Tip

To identify an equivalent form, simplify the square root first. चरण 1: \(75=25 \times 3\) है। चरण 2: \(\sqrt{75}=5\sqrt{3}\)। चरण 3: बराबर रूप पहचानने के लिए पहले वर्गमूल को सरल करें।

\(\sqrt{7}\) का लगभग मान किसके सबसे निकट है?

The approximate value of \(\sqrt{7}\) is closest to which number?

Explanation opens after your attempt
Correct Answer

B. (2.65)

Step 1

Concept

The value of \(\sqrt{7}\) is about (2.646).

Step 2

Why this answer is correct

Among the options, (2.65) is closest.

Step 3

Exam Tip

For estimation, use nearby perfect squares (4) and (9) to understand the range. चरण 1: \(\sqrt{7}\) का मान लगभग (2.646) है। चरण 2: दिए गए विकल्पों में (2.65) सबसे निकट है। चरण 3: अनुमान में पास के पूर्ण वर्ग (4) और (9) से सीमा समझें।

\(\frac{\sqrt{7}}{3}\) कैसी संख्या है?

What type of number is \(\frac{\sqrt{7}}{3}\)?

Explanation opens after your attempt
Correct Answer

B. अपरिमेयIrrational

Step 1

Concept

\(\sqrt{7}\) is irrational.

Step 2

Why this answer is correct

Dividing it by the non-zero rational number (3) keeps the result irrational.

Step 3

Exam Tip

Division by a non-zero rational number does not remove irrationality. चरण 1: \(\sqrt{7}\) अपरिमेय है। चरण 2: इसे अशून्य परिमेय संख्या (3) से भाग देने पर परिणाम अपरिमेय रहता है। चरण 3: अशून्य परिमेय से भाग करने पर अपरिमेयता समाप्त नहीं होती।

\(\sqrt{7}+4\) के बारे में सही कथन कौन-सा है?

Which statement is correct about \(\sqrt{7}+4\)?

Explanation opens after your attempt
Correct Answer

C. यह अपरिमेय हैIt is irrational

Step 1

Concept

\(\sqrt{7}\) is irrational and (4) is rational.

Step 2

Why this answer is correct

Adding a rational number does not remove the irrational part.

Step 3

Exam Tip

The sum of a rational and an irrational number is generally irrational. चरण 1: \(\sqrt{7}\) अपरिमेय है और (4) परिमेय है। चरण 2: परिमेय संख्या जोड़ने से अपरिमेय भाग समाप्त नहीं होता। चरण 3: परिमेय और अपरिमेय संख्या का योग सामान्यतः अपरिमेय होता है।
