Question

How do I write this without an exponent?
\[(-9^{1})^{-2} \]

Answer 1

Write it like this..
-9^1x-2
-9^-2
So it becomes inverse of that because the power is negative.
So it'll become
1/9^2
or
1/81

Answer 2

But -2 is a power.

Answer 3

Okay first
-9^1
is
-9 right?
Got that?? :)

Answer 4

Yaa

Answer 5

Okay so after we got that we have
-9^-2 right?
Let me explain that to you with an example..
Let us say we have (ab)^-3
It can also be written as: 1/(ab)^3
Did you get that?

Answer 6

Whenevr a power is negative integer then the term inverses.
That is a rule. :)
