Solving Logarithmic Equations

Question 2
2.

The first step in solving a basic logarithmic equation is to use the base on both sides of the problem.

Question 3
3.

Put the steps in order to solve: \log_8(x)=2

  1. 8^{\log_8(x)}=8^2
  2. x=64
  3. \log_8(x)=2
Question 4
4.

Put the steps in order to solve: \log_x(81)=\frac{4}{3}

  1. \log_x(81)=\frac{4}{3}
  2. 81=x^\frac{4}{3}
  3. x=27
  4. 81^\frac{3}{4}=(x^\frac{4}{3})^{\frac{3}{4}}
  5. x^{\log_x(81)}=x^\frac{4}{3}
Question 5
5.

Solve: \log_{10}{x}=2

Question 6
6.

Solve \log_{x}{5}=\frac{1}{4}

Question 7
7.

Solve: \log_{x}{256}=4

Question 8
8.

Solve \log_{2}{256}=x
