It is 3^X=18 using the first law of logarithms. X = 2.62
This is as simple as it gets :) Better touch up on your math skills :P

This means that 3^x=18 so x = ln(18)/ln(3)

log_3(18) = x
x = [log(18)]/[log(3)]
x = 2.63092975357144

Log (3) 18 = x is equal to 3 raised to the x = 18. So it all equals "3^x = 18."
