What is the exponent rule of log?
In mathematics, an exponential function is a function of form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.
How do you solve exponential logs?
Log exponent rule states that log base b of ax is equal to x times log base b of a i.e., logbax = x logba.

Changing from Exponential to Logarithmic Form
To change from exponential form to logarithmic form, identify the base of the exponential equation and move the base to the other side of the equal sign and add the word “log” Do not move anything but the base, the other numbers or variables will not change sides |
