यदि (x+y+z=0), तो \(x^3+y^3+z^3\) किसके बराबर होगा?
If (x+y+z=0), then \(x^3+y^3+z^3\) will be equal to what?
Explanation opens after your attempt
B. ( 3xyz )
Concept
The identity gives \(x^3+y^3+z^3-3xyz=0\). Exam tip: when (x+y+z=0), remember (3xyz).
Why this answer is correct
The correct answer is B. ( 3xyz ). The identity gives \(x^3+y^3+z^3-3xyz=0\). Exam tip: when (x+y+z=0), remember (3xyz).
Exam Tip
पहचान से \(x^3+y^3+z^3-3xyz=0\) मिलता है। परीक्षा में शर्त (x+y+z=0) मिलते ही (3xyz) याद करें।
