Question

simplify (y^-7*y^-3)^-1

Answer 1

\[(y^{-7} * 7^{-3})^{-1}\] ^^^^ that?

Answer 2

that is the correct problem the way you set it up but I could not figure out how to set it up correctly

Answer 3

(y^{-7} * 7^{-3})^{-1} in the equation bar

Answer 4

ok so, do you know what we do with variables to powers when multiplied?

Answer 5

subtract right

Answer 6

that's divide, so if we multiply we add them

Answer 7

Thanks.

Answer 8

lol are you done?

Answer 9

\[(1/(y^7*y^3))^(-1) \]\[\left(1\left/\left(y^{10}\right)\right.\right){}^{\wedge}(-1) \]\[\left(\frac{1}{y^{10}}\right){}^{\wedge}(-1) \]\[y^{10} \]
