How would I isolate the variable x in the following statement?
The answer would look like x=something
y = a(r)^x divide both sides by a
(y / a) = r^x take the log of both sides
log ( y / a) = log r^x and by a log property we can write
log ( y / a) = x * log r divide both sides by log r
log ( y / a) / log r = x
