Answer:
6561
Explanation:
So, lets just go over what we know:
The exponent is 4, meaning the number will be multiplyied by itself 4 times.
The number is -9, so we are going to multiply it by -9, 4 times.
We can think of it like this:
9*9*9*9
I used postive nines instead of negative nine since the sign will be postive.(Because its a even exponent)
Now lets solve:
9*9*9*9
=
81*9*9
=
729*9
=
6561
So this is the answer!
Hope it helps! :)
