Copy these equations and solve for $x$. You should be able to do all these problems without a calculator.

1. $\log_x(25)=1$ 

   Hint (a):

   Rewrite the equation in exponential form:

2. $x=\log_3(9)$ 

   Hint (b):

   $3$ to what power is $9$?

3. $3=\log_7(x)$ 

4. $\log_3(x)=\frac{1}{2}$ 

   Answer (d):

   $x=\sqrt{3}$

5. $3=\log_x(27)$ 

6. $\log_{10}(10000)=x$
