5-86.

Solve each logarithmic equation.  Homework Help ✎

1. $\log(x)+\log(x)=4$

$\log(x^2)=4$

Rewrite the equation in exponential form. Remember that the base in this case is $10$.

Recall that the domain of the basic logarithmic function is $x>0$.

1. $\log_2(16)−\log_2(x)=5$

$\log_2\left(\frac{16}{x}\right)=5$

1. $\log_3(3^8)=x$

Rewrite the equation in exponential form.
