Question

determine y, se log (log y na base 3) na base 25 = 1/2

Answer 1

$\log_ab=c$
$a^c=b$

$\log_{25}(\log_3y)=\frac12$

$25^{\frac12}=\log_3y$

$\sqrt{25}=\log_3y$

$\log_3y=5$

$3^5=y$

$y=243$

Answer 2

log25(log3(y)) = 1/2

log(log(y)/log(3)) = log(25)/2 

log(y)/log(3) = 5

log(y) = 5*log(3) = log(3^5)

y = 3^5 = 243
