Question

nesha97 · Answer

$$a^{m}\times a ^{3}=\frac{ 1 }{ a ^{2} }$$

mathmale · Answer

Have you compiled a list of "rules of exponentiation?"  That might help.

Can you combine a^m and a^3 into a single expression with base a?      a^?

Can you re-write 1 / (a^2)  so that the base is still a but the exponent is negative?

If you have to say "no," please review those rules of exponentiation, and then come back.

$$a^{-1}=\frac{1}{a}$$
$$a^{-2}=\frac{1}{a^2}$$
$$a^{-n}=\frac{1}{a^n}$$

im just confused because a can equal any number right?

sooobored · Answer

yea, a is a variable
a could even be another variable

Again:  Please look up and review "rules of exponentiation."   Decide which rule or rules applies to the situation you're dealing with here.
