Ok, when you multiply variable with exponents you just add the exponents together

so 5+2=7

so therefore its

\[n^{7}\]

Answer 8

ok i get that

Answer 9

Alright, what other types of problems do you need help with

Answer 10

x-4 x x-4 x x4

Answer 11

Hmm, is that

\[(x-4)(x-4)x^{4}\]

Answer 12

its x^-4 times x^-4 times x^4

Answer 13

Ok, add the exponents again, left to right

what do you get?

Answer 14

-4

Answer 15

Right, so you end up with x^-4

when there is a negative exponent it can be written like this, put a 1 over it and make the exponent positive

\[\large 1/x^{4}\]
