Question

A questao a Seguir Resolva 32ⁿ=128

Answer 1

$32^n=128\\ \\ (2^5)^n=2^7\\ \\ 2^{5n}=2^7\\ \\ 5n=7\\ \\ n=\frac{7}{5}$

Answer 2

$\mathsf{32^{n} = 128 } \\ \mathsf{Como \ 32 = 2^{5} \ e \ 128 = 2^{6} \Rightarrow } \\ \mathsf{ (2^{5})^{n} = 2^{7}} \\ \mathsf{ 2^{5n} = 2^{7} } \\ \mathsf{5n = 7 } \\ \mathsf{n = \frac{7}{5}}$
