Answer 2

you just need to plug in x = 3 and y = -1

Answer 3

1/(3^(-2) * (3)^(-4) * (-1)^2) = ?

Answer 4

-0.001

Answer 5

let's start with the denominator, one factor at a time

3^(-2) = ?

Answer 6

0.01,that's what the calculator says, or is it -9?

Answer 12

hint: (3)^(-4) = 1/(3^4), which, as a fraction, = ?

Answer 13

so 1/100

Answer 14

what is 3^4 = ?

Answer 15

81

Answer 16

good, so( 3)^(-4) = 1/(3^4) = 1/81

so putting everything back together

1/(1/81 * 1/9) = ?

Answer 17

1/729

Answer 18

almost

1/81 * 1/9 gives us 1/729

so we end up with 1/(1/729) = 729 = your sol'n

Answer 19

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
