PLS HELP!!!
@Vocaloid
you just need to plug in x = 3 and y = -1
1/(3^(-2) * (3)^(-4) * (-1)^2) = ?
-0.001
let's start with the denominator, one factor at a time 3^(-2) = ?
0.01,that's what the calculator says, or is it -9?
as a fraction, it is 1/9
*0.1
let's stay in fractions for now (3)^(-4) = ?
0.01

hint: (3)^(-4) = 1/(3^4), which, as a fraction, = ?
so 1/100
what is 3^4 = ?
81
good, so( 3)^(-4) = 1/(3^4) = 1/81 so putting everything back together 1/(1/81 * 1/9) = ?
1/729
almost 1/81 * 1/9 gives us 1/729 so we end up with 1/(1/729) = 729 = your sol'n
to divide fractions, we flip the second fraction and change the division sign to a multiplication sign so 1/(1/729) = 1 * (729/1) = 729
