Question

please give the answer


a m ÷ a n =​

Answer 1

$am \div an \\ = > \: \: \frac{am}{an } (a \: are \: cancelled) \\ = > \: \frac{m}{n}$

Answer 2

We know that,

$a^ma^n = a^m+^n$

That is,

mn=m+n.

Now,

m(n−2)+n(m−2)=mn−2m+nm−2n

=2mn−2(m+n)=2(m+n)−2(m+n)=0

∴ The required answer is 0.
