How do you solve #z^(-1/4) = 1/3#? Algebra Exponents and Exponential Functions Negative Exponents 1 Answer 256 Jan 18, 2017 #z^(-1/4)=1/3 <=> z=81# Explanation: #z^(-1/4)=1/3# #<=># First since #x^(-1)=1/x#, and #x^(ab)=(x^a)^b# #z^((-1)(1/4))=(z^(1/4))^(-1)=1/z^(1/4)=1/3# #<=># #1=z^(1/4)/3# multiply both sides by #z^(1/4)# #<=># #3=z^(1/4)# multiply both sides by 3 #<=># #3^4=(z^(1/4))^4# raise both sides to the power of 4 #<=># #3^4=z# #<=># #(3^2)^2=(3^2)(3^2)=9(9)=ul(81=z)# Answer link Related questions What are Negative Exponents?
