Answer:
option (a)
(a³-b³)^1/4
Step-by-step explanation:
Given in the question an expression
4√a³-b³
To find,
this expression without radicals
There is another way to represent the taking of a root. You can use rational exponents instead of a radical. A rational exponent is an exponent that is a fraction. a√x = (x)1/a
Example
√a = a^1/2
∛a = a^1/3
So, similarly the expression 4√a³-b³ = (a³-b³)^1/4
