Hello

How would I isolate the variable x in the following statement?

y=a(r)^{x}

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
