Question

When 27x2z/-3x2z4 is completely simplified, the exponent on the variable z is _____.

Answer 1

0

Explanation:

(27x)(2z)/(-3x)(2z)(4)

-9/4

When you divide 2z by 2z, there is an imaginary exponent 1 on the z's. The rule for dividing numbers with exponents is to subtract the exponents. So, 2z/2z = 1(z^1-1) = 1(z^0) = 1
