Question

Another exponential equation

4^x^2 = (16^x)(64^x+2)

Answer 1

interesting...let me show a magic trick
\[\huge \implies 4^{x^2} = (4^{2x})(4^{3(x+2)})\]
do you see what to do now?

Answer 2

since there's two fours on one side, which 4 do i choose to get rid of?

Answer 3

or do i multiply the fours together on the right side?
