This is because we want to avoid having negative numbers under the square root. So we make the radicand to be 0 or larger.

Step-by-step explanation:
They don't look alike
The number is 15,
I really don’t know if there’s such a strategy to find this out, I just used trial & error:
(a*4)+(a*3)=35
(5*4)+(5*3)=35
20+15=35
Fourth root (3/2x)
= [fourth root {3*(2x)^3} / {2x * (2x)^3}]
= [fourth root (3*8x^3}) /(2x)^4]
= [fourth root (24x^3)] / 2x
answer is B. second one
