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.
True
False
Question 3
3.
Put the steps in order to solve: \log_8(x)=2
\log_8(x)=2
8^{\log_8(x)}=8^2
x=64
Question 4
4.
Put the steps in order to solve: \log_x(81)=\frac{4}{3}
x^{\log_x(81)}=x^\frac{4}{3}
\log_x(81)=\frac{4}{3}
81=x^\frac{4}{3}
x=27
81^\frac{3}{4}=(x^\frac{4}{3})^{\frac{3}{4}}

What is the first step when solving a basic logarithmic equation?
Question 11
11.
Choose all that are true
I am confident in this lesson.
I would like some assistance.
I can solve for the base: \log_{x}{64}=2
I can solve for the arguement:\log_{8}{x}=2
I can evaluate the logartithm: \log_{8}{64}=x
