Simplify

v^-5*v^2

Write your answer with a positive exponent only.

Answer 1

add the exponents
\[v^{-5}*v^2=v^{-5+2}\]

Answer 2

but wouldn't that be v^-3?

Answer 3

yes. and to make it a positive exponent, move it to the denominator.

Answer 4

oh ya!!! THANK YOU SMMMM!!

Answer 5

you're welcome. And that works both ways. When you want to change the sign of the exponent, move it to the other side of the fraction line.
