Answer 1

• When solving logarithmic equations, convert them back to exponential form and figure out what the missing piece should be to make the statement true.

Question 2

• A log written without a “b” value is the common log.

y = logx

In a common log, the “b” value is understood to be 10. In other words, y = logx is equivalent to the statement 10y = x.

Answer 2

• A log written without a “b” value is the common log.

y = logx

In a common log, the “b” value is understood to be 10. In other words, y = logx is equivalent to the statement 10y = x.
