Rewrite [tex]\sqrt{4^{x } }[/tex] as [tex]4^{0.5x}[/tex] because [tex]\sqrt{a}[/tex]=[tex]a^{0.5}[/tex]
[tex]4^{0.5x }[/tex]=16=4²
The exponents can be set equal as the bases are equal
0.5x=2
x=4
[tex]4^{0.5x }[/tex]=16=4²
The exponents can be set equal as the bases are equal
0.5x=2
x=4

Perfect. Direct. Correct.
