Question

calcule o valor de x em:

a- log ₄⁴ = x

b- log ₂ 32 = x

c- log₅ 0,04 = x

Answer 1

Calcule o valor de x em:

a- log ₄⁴ = x
$4^{x} = 4$
$x = 1$

b- log ₂ 32 = x
$2^{x} = 2^{5} x = 5$

c- log₅ 0,04 = x
$5^{x} = 0,04$
$0,04 = \frac{4}{100} = \frac{1}{25} = \frac{1}{ 5^{2} } = 5^{-2}$
x = -2
