How do you solve the exponential equation #8^(5x)=16^(3x+4)#? Precalculus Algebraic Modeling Solving Problems Algebraically and Graphically 1 Answer Eddie Mar 8, 2017 #implies x = 16/3# Explanation: #8^(5x)=16^(3x+4)# #implies (2^3)^(5x)=(2^4)^(3x+4)# #implies 2^(15x)=2^(4(3x+4))# #implies 15x = 12x+16# #implies x = 16/3# Answer link Related questions What does it mean to solve a problem algebraically?
