Question 61/181 Medium Mathematics Polynomials Operations on real numbers and the laws of exponents Class 10 Level 45

यदि \(\dfrac{2^5 \times 8}{4^2}\) को घात के रूप में सरल किया जाए, तो इसका मान क्या होगा?

If \(\dfrac{2^5 \times 8}{4^2}\) is simplified using exponents, what is its value?

Explanation opens after your attempt

Correct Answer

A. (,16,)

Step 1

Concept

Here \(8=2^3\) and (4²=\(2^2\)²=2⁴), so \(\dfrac{2^5 \times 2^3}{2^4}=2^4=16\). In exams, converting numbers to the same base is useful.

Step 2

Why this answer is correct

The correct answer is A. (,16,). Here \(8=2^3\) and (4²=\(2^2\)²=2⁴), so \(\dfrac{2^5 \times 2^3}{2^4}=2^4=16\). In exams, converting numbers to the same base is useful.

Step 3

Exam Tip

यहां \(8=2^3\) और (4²=\(2^2\)²=2⁴), इसलिए \(\dfrac{2^5 \times 2^3}{2^4}=2^4=16\)। परीक्षा में सभी संख्याओं को समान आधार में बदलना उपयोगी होता है।
