8th grade math..I don't understand it 10 points <3

3^4 × 3^-2
3^4 × 3^x
3^4 × 3^4
3^a × 3^-2
3^a × 3^x
3^a × 3^4
-3^2 × 3^-2
-3^2 × 3^x
-3^2 × 3^4

thanks :}

You guys are ridiculous...
There are exponential rules you should focus on here!
If we have the same base we can add the exponents which is exactly what you have here. I will walk you through one of them and you can do the rest.
3^a × 3^x
Since we have the same base here (3) we can simply add the exponents.
3^a × 3^x = 3^(a+x)
So for your first problem this would be...
3^4 × 3^-2 = 3^(4+(-2)) = 3^2 = 9
For the cases where you have -3 it is being squared so you don't have to worry because a negative times a negative is positive!
Hope this helps you get started.

Lazy...

just type that stuff in your calculator! and then press enter.
it should be easy enough!

all of these are exponents. the answer to the third one is below

3^4 x 3^4
3x3x3x3=81 x
3x3x3x3=81
=6561
