a) 2^(x+3)= 4^(2x) make base number the same 2^(x+3)= 2^2 (2x) set the exponents equal to eachother x+3=2 (2x) x+3=4x -x both sides 3=3x ÷3 both sides x=1
b) 16^(1/5)×2^(x)=8^(3/4) make base same number 2^4 (1/5)×2^(x)=2^3 (3/4) 2^(4/5)×2^(x)=2^(9/4) set exponents 4/5 +x=9/4 -4/5 both sides x= 29/20
