Answer 1

Answer:

$a^{4} *b^{4}$  

Step-by-step explanation:

Given :   $(ab)^{4}$

We need to find which of the following in the given options is equivalent to the given expression .

To solve this we will consider the rule of exponent :

$a^{n} *b^{n} = (ab)^{n}$

In this put n = 4

$a^{4} *b^{4} = (ab)^{4}$

Thus we can see that the option b is correct i.e.

$a^{4} *b^{4}$
