Question: If the square root of x is the cube root of y, then the relation between x and y is
Options:
A) $ x^{3}=y^{2} $
B) $ x^{2}=y^{3} $
C) $ x=y $
D) $ x^{6}=y^{5} $
Show Answer
Answer:
Correct Answer: A
Solution:
- Given, $ \sqrt{x}=\sqrt[3]{y} $
$ \Rightarrow $ $ {x^{\frac{1}{2}}}={y^{\frac{1}{3}}} $
On taking power of 6 both sides,
$ {{({x^{\frac{1}{2}}})}^{6}}={{({y^{\frac{1}{3}}})}^{6}}\Rightarrow x^{3}=y^{2} $
