Verified Answer :

when you have 2 exponents its always the multiple of them : 4*8= 32
N^32

Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

\((N^4)^8\)

As we know that

\((a^n)^m=a^{n\times m}=a^{nm}\)

\(N^{4\times 8}\\\\=N^{32}\)

Hence, Option 'B' is correct.
