Question

if a^m . a^n = a^mn then m(n-2) +n(m-2) is​

Answer 1

Answer:

As given : a^m.a^n = a^mn , Therefore We can write it like this :

a^ m+n = amn ,

Now on comparing powers of a , we get

m+n = mn

Step-by-step explanation:

Taking , m(n-2) + n(m-2)

mn - 2 m + mn - 2 n

2 mn -2 m - 2 n

2 mn - 2 (m+n)

2mn - 2 mn = 0 Ans. ( Because here we have m+n = mn ) .
