Verified Answer :

(ab)^4 means ab times itselv 4 times
multicplication is comutaive so
a^4b^4

2nd option is answer

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.

\(a^{4} *b^{4}\)
