Question

Me ajudem nesse dever........

Answer 1

Resposta:

${4}^{n} = 8 \\ {2}^{ 2n } = {2}^{3} \\ 2n = 3 \\ n = \frac{3}{2}$

${4}^{p} = 4 \\ {4}^{p} = {4}^{1} \\ p = 1$

${4}^{4 - n - p} = {4}^{4 - \frac{3}{2} - 1} = {4}^{ \frac{8 - 3 - 2}{2} } = {4}^{ \frac{3}{2} } = \sqrt{ {4}^{3} } = \sqrt{64} = 8$
