Can anyone do it ?

Answer 1

$question$

a^m * a^-n = ?

$answer$

am * an = a(m+n)

$extra \: information$

am * an = a(m+n) says that when you take a number, a, multiplied by itself m times, and multiply that by the same number a multiplied by itself n times, it's the same as taking that number a and raising it to a power equal to the sum of m + n.
