log_color(red)5 y = 2 " "rArr " " color(red)5^2 = y

Explanation:

log form is written as " "log_a b = c
exponential (index) form is " "a^c = b

The two forms are interchangeable.

To make it easier remember:

"The base stays the base and the other two swop around"

log_color(red)5 y = 2 " "rArr " " color(red)5^2 = y
