Question

log de 2x+10 na base 4 = a 2

Answer 1

$log_{4}2x+10=2$
$a ^{x}=b$ tal que:
$4^{2}=2x+10$ 
16=2x+10
$16-10=2x$
6=2x
$\frac{6}{2} = x$
x=3

Answer 2

   log de 2x+10 na base 4 = a 


   Log  2x + 10 = 4
        2
 
       2x + 10 = 2^4
         2x + 10 = 16
           2x = 16 - 10
            2x = 6
 
              x = 3
