Answer 2

Answer:

The answer is 0.

STEP-BY-STEP

Here, in this question, it is given that a^m into a^n = a^mn,

we can conclude that m+n= mn (Since, a^m x a^n = a^mn)

Now, we need to simply m(n-2) + n(m-2)

m(n-2) + n(m-2)

= mn - 2m + mn - 2n

= 2mn -2(m+n)

= 2mn - 2(mn) (Since, we concluded, m+n=mn)

= 2mn - 2mn= 0

Therefore, the answer to this question is 0.
