Author: Muft Shiksha Editorial Team Published:
Explanation opens after your attempt
Correct Answer

A. ((x+4)\(x^2-4x+16\))

Step 1

Concept

Since \(64=4^3\), use the \(a^3+b^3\) formula. Exam tip: keep the middle sign negative in sum of cubes.

Step 2

Why this answer is correct

The correct answer is A. ((x+4)\(x^2-4x+16\)). Since \(64=4^3\), use the \(a^3+b^3\) formula. Exam tip: keep the middle sign negative in sum of cubes.

Step 3

Exam Tip

\(64=4^3\), इसलिए \(x^3+64\) में \(a^3+b^3\) का सूत्र लगेगा। परीक्षा में योग के घन में बीच का चिन्ह ऋणात्मक रखें।
