Question

calcule o valor de x

Answer 1

Resposta:

A)

${1024}^{x} = 2 \\ { {2}^{(10)} }^{x} = {2}^{1} \\ 10x = 1 \\ x = \frac{1}{10}$

B)

$\frac{1}{100} = {2}^{x} \\ \frac{1}{ {10}^{2} } = {2}^{x} \\ 1 \times {10}^{ - 2} = {2}^{x} \\ log( {10}^{ - 2} ) = log({2}^{x}) \\ - 2 log(10) = x log(2) \\ - 2 \times 1 = x \times 0.3 \\ x = \frac{ - 2}{0.3} \\ x = - 6.66$
