Question

Dados log2= x e log3= y,determine : Log de raiz cubica de 12

Answer 1

㏒2=x
㏒3=y
                      ㏒∛12

                   1/3 ㏒12

                   1/3㏒2.2.3
 
                   1/3(㏒2+㏒2+㏒3)

                   1/3(x+x+y)

                       2x+y/3

                      
                  

Answer 2

Vejamos:

log∛12 = log 12^1/3 = 1/3log12 = 1/3log2*2*3 = 1/3(x+x+y)

logo, log∛12 = (2x + y)/3
