Question

Resolva a equação exponenciais:

a) $(2^{X})^{X} = 16$

Answer 1

veja...

$(2^x)^x=16 \\ \\\not2 ^{ x^{2} }=\not2^4 \\ \\ x^{2} =4 \\ \\ x=\pm \sqrt{4} \\ \\ x=\pm2 \\ \\ S=\{-2,2\}$

Answer 2

$\mathsf{(2^{x})^{x}=16}\\\\ \mathsf{2^{x^{2}}=2^{4}}\\\\ \mathsf{x^{2}=4}\\\\ \mathsf{x=\pm \sqrt{4}}\\\\ \mathsf{x=\pm 2}$


$\mathsf{S=\{-2,2\}}$

Bons estudos! :-)
