Step 2

Why this answer is correct

The correct answer is A. \(3\sqrt{3}\). \(\sqrt{12}=2\sqrt{3}\), so \(\sqrt{3}+\sqrt{12}=3\sqrt{3}\). In exams make radicals like terms before adding.

Step 3

Exam Tip

\(\sqrt{12}=2\sqrt{3}\), इसलिए \(\sqrt{3}+\sqrt{12}=3\sqrt{3}\) है। परीक्षा में मूलों को जोड़ने से पहले समान मूल बनाएं।

यदि \(\frac{154}{2\cdot5^2\cdot7\cdot11}\) को सरलतम रूप में लिखा जाए, तो उसका दशमलव प्रसार कैसा होगा?

If \(\frac{154}{2\cdot5^2\cdot7\cdot11}\) is written in lowest form, what type of decimal expansion will it have?

Explanation opens after your attempt
Correct Answer

A. समाप्त दशमलवTerminating decimal

Step 1

Concept

\(154=2\cdot7\cdot11\), so after cancellation only \(5^2\) remains in the denominator. In exams decide from the denominator in lowest form.

Step 2

Why this answer is correct

The correct answer is A. समाप्त दशमलव / Terminating decimal. \(154=2\cdot7\cdot11\), so after cancellation only \(5^2\) remains in the denominator. In exams decide from the denominator in lowest form.

Step 3

Exam Tip

\(154=2\cdot7\cdot11\), इसलिए कटने के बाद हर में केवल \(5^2\) बचता है। परीक्षा में निर्णय हमेशा सरलतम रूप के हर से करें।

यदि \(\frac{35}{2^2\cdot5\cdot7^2}\) को सरलतम रूप में लिखा जाए, तो उसका दशमलव प्रसार कैसा होगा?

If \(\frac{35}{2^2\cdot5\cdot7^2}\) is written in lowest form, what type of decimal expansion will it have?

Correct Answer

A. अनवसानी आवर्तीNon-terminating recurring

Step 1

Concept

After simplification, (7) remains in the denominator, so the decimal is non-terminating recurring. In exams do not decide only from the original denominator.

Step 2

Why this answer is correct

The correct answer is A. अनवसानी आवर्ती / Non-terminating recurring. After simplification, (7) remains in the denominator, so the decimal is non-terminating recurring. In exams do not decide only from the original denominator.

Step 3

Exam Tip

सरलीकरण के बाद हर में (7) बचता है, इसलिए दशमलव अनवसानी आवर्ती होगा। परीक्षा में केवल मूल हर देखकर निर्णय न लें।
