I dont understand your edited question.....

first you put 3(18)=?

Then you edited it to Log 3(18)= 3 How?

for my fist answer I used the tiger algebra calculator

for your edited question i have no answer......

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.
