Question

solve: a^2 · a^3 · a^-4

Answer 1

do you know the answer?

Answer 2

use these formula ..a^-n = 1/a^n , a^n . a^m = a^(n+m) and a^n/a^m = a^(n-m)
and you can get the answer quick

Answer 3

it's not a^9 though..

Answer 4

ofcourse it's not, one of the power is negative...check that again :)

Answer 5

see that's what confuses me, but I thought when you flip the exponent to make it positive, you add it as a positive exponent?

Answer 6
