Question: If $ Z=A^{3} $ , then $ \frac{\Delta Z}{Z}=____ $
Options:
A) $ \frac{\Delta A^{3}}{A} $
B) $ {{( \frac{\Delta {{A}^{{}}}}{A} )}^{3}} $
C) $ 3( \frac{\Delta {{A}^{{}}}}{A} ) $
D) $ {{( \frac{\Delta {{A}^{{}}}}{A} )}^{1/3}} $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] as $ z=A^{3} $ , so $ \frac{\Delta z}{z}=3\frac{\Delta A}{A} $
