Question

$10^{2y} = 25 \\ \\10^{-y}$

Answer 1

Respuesta: y=  $\frac{ln(5)}{ln(10)}$ = 0.69897

Explicación paso a paso:

ln($10^{2y}$) = ln (25)

2y ln (10) = ln (25)   , multiplicar ambos lados por : 2 ln(10)

$\frac{2y ln (10)}{2ln(10)} = \frac{ln (25)}{2ln(10)}$

y= $\frac{ln(5)}{ln(10)}$

y=0.69897
