Question

Vamos determinar a solucao da equacao:
2 elevado x . 8 = 512

Answer 1

${2}^{x \times 8} = 512 \\ {2}^{x \times 8} = {2}^{9} \\ 8x = 9 \\ x = \frac{9}{8} \\ {2}^{ \frac{9}{8} \times 8 } = 512 \\ {2}^{ \frac{72}{8} } = 512 \\ {2}^{9 } = 512$

Answer 2

${2}^{x.8} = 512 \\ {2}^{x.8} = {2}^{9} \\ x.8 = 9 \\ x = 9 \div 8$
