Which shows the following expression using positive exponents? a^3b^-2/ab^-4, a ≠ 0, b ≠ 0 a a^3b^-4/ab^-2 b ab^4/a^3b^2 c -a^3b^4/ab^2 d a^3b^4/ab^2

A ^ 3b ^ -2 / ab ^ -4, a ≠ 0, b ≠ 0
 First we rewrite the expression respecting the properties of the exponents.
 b ^ -2 = 1 / b ^ 2
 1 / b ^ -4 = b ^ 4
 We have then:
 a ^ 3b ^ -2 / ab ^ -4
 a ^ 3b ^ 4 / ab ^ 2
 
 An expression using positive exponents is
 D a^3b^4/ab^2

Byou start by adding them all and setting them equal to 180 since that is half of the total degrees in a circle.(2x+8) + (3x-14) + (3x-14) = 1808x-20 = 1808x = 200x = 25
