तीन लगातार पूर्णांकों का गुणनफल 6 से विभाज्य क्यों होता है?

Why is the product of three consecutive integers divisible by 6?

Explanation opens after your attempt
Correct Answer

A. क्योंकि उनमें एक 2 से और एक 3 से विभाज्य होता हैBecause one of them is divisible by 2 and one is divisible by 3

Step 1

Concept

Among two consecutive integers, one is even, so a factor 2 is present.

संख्या रेखा पर \(\sqrt{5}\) किस दो क्रमागत पूर्णांकों के बीच होगा?

Between which two consecutive integers will \(\sqrt{5}\) lie on the number line?

Explanation opens after your attempt
Correct Answer

B. (2) और (3)(2) and (3)

Step 1

Concept

Since \(2^2<5<3^2\), \(\sqrt{5}\) lies between (2) and (3). Use squares to locate square roots quickly.

Step 2

Why this answer is correct

The correct answer is B. (2) और (3) / (2) and (3). Since \(2^2<5<3^2\), \(\sqrt{5}\) lies between (2) and (3). Use squares to locate square roots quickly.

संख्या रेखा पर \(\sqrt{13}\) किस दो पूर्णांकों के बीच स्थित होगा?

Between which two integers will \(\sqrt{13}\) lie on the number line?

Explanation opens after your attempt
Correct Answer

A. (3) और (4)(3) and (4)

Step 1

Concept

Since \(3^2=9\) and \(4^2=16\), \(\sqrt{13}\) lies between (3) and (4). Use nearby perfect squares to locate square roots.

Step 2

Why this answer is correct

The correct answer is A. (3) और (4) / (3) and (4). Since \(3^2=9\) and \(4^2=16\), \(\sqrt{13}\) lies between (3) and (4). Use nearby perfect squares to locate square roots.

Step 3

Exam Tip

क्योंकि \(3^2=9\) और \(4^2=16\), इसलिए \(\sqrt{13}\) (3) और (4) के बीच है। वर्गमूल की स्थिति के लिए निकट पूर्ण वर्ग देखें।

संख्या रेखा पर \(-\sqrt{8}\) किस दो पूर्णांकों के बीच होगा?

Between which two integers will \(-\sqrt{8}\) lie on the number line?

Explanation opens after your attempt
Correct Answer

A. (-3) और (-2)(-3) and (-2)

Step 1

Concept

\(\sqrt{8}\) lies between (2) and (3), so \(-\sqrt{8}\) lies between (-3) and (-2). The negative sign changes the direction.

Step 2

Why this answer is correct

The correct answer is A. (-3) और (-2) / (-3) and (-2). \(\sqrt{8}\) lies between (2) and (3), so \(-\sqrt{8}\) lies between (-3) and (-2). The negative sign changes the direction.

Step 3

Exam Tip

\(\sqrt{8}\) (2) और (3) के बीच है, इसलिए \(-\sqrt{8}\) (-3) और (-2) के बीच होगा। ऋण चिह्न दिशा बदल देता है।
