Answered by Long Division is fun
I have no idea how long ago this was but if you still need the answers:
Question 1: 1/9
(Use the product rule of exponents to make 3^7 x 3^-9 into 3^-2 {7 + -9 = -2} which is 1/3^2 which is also 1/9)
Question 2: 64
(Use the quotient rule of exponents to make 2^2 / 2^-4 into 2^6 {2 - -4 = 6}, which solved is 64)
Question 3: -8/25
Question 4: 1/81
(Use the Zero power rule of exponents to make the numerator 1, then solve for 3^4, which is 81)
Question 5:
7/16
