_7 means under the log.
-
y = log₇ x
to find its inverse, switch x and y and solve for y
x = log₇ y
raise both sides to the 7th power to cancel the logs
7ˣ =y
so the inverse of the equation is
y = 7ˣ
to find its inverse, switch x and y and solve for y
x = log₇ y
raise both sides to the 7th power to cancel the logs
7ˣ =y
so the inverse of the equation is
y = 7ˣ
