Question

Obtenha em cada caso ,o valor de x
A) log(3)x = log(3) 24 =

B) log(3) x = 3 =

C) log(3) (2x+5)=6 =

Answer 1

A) log(3)x = log(3) 24 ==> x = 24
===============================================
B) log(3) x = 3 ==> x = 3^3 ==> x =  27
===================================================
C) log(3) (2x+5)=6 ==> 2x + 5 = 3^6 ==> 2x = 729 - 5 ==> 2x = 724 ==> x= 362
