I remember this

$$log_{10}100=2\qquad because \qquad 10^2=100$$

A log is a power

so

$$if \;\;x=log_3 18\;\;then \;\;18=3^x$$

I will use change of base log law to solve this

$$log_y x = \frac{log_a x}{log_a y}$$

$$log_318=\frac{log_{10}18}{log_{10}3}\approx 2.6309$$

So it will only 'equal' 3 if it is rounded to the nearest whole number.
