Question

8.....,,,,,,,,,,,,,,,,

Answer 1

option (a)

(a³-b³)^1/4

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
