Question

Can someone verify that the sign would be a negative or positive?

(9m)^-2 =
-81m is what I came up with.

Answer 1

Hi Satellite :)

Answer 2

take the reciprocal and square it, do not make it negative
hello

Answer 3

so it's 81m

Answer 4

math is weird but not that weird
if it is supposed to be negative you would see a big fat minus sign out front

Answer 5

well, i am trying to get the hang of the signs ...doing my best lol

Answer 6

\[b^{-n}=\frac{1}{b^n}\] so
\[(9m)^{-2}=\frac{1}{(9m)^2}\]

Answer 7

wow, way off. lol

Answer 8

the minus sign in the exponent does not mean make it negative
the minus sign in the exponent means take the reciprocal

Answer 9

so for example
\[3^{-2}=\frac{1}{9}\]

Answer 10

so its 1/(9m)^2

Answer 11

says simplify
is that simplified?

Answer 12

you could write
\[\frac{1}{81m^2}\]if you like
