The logarithm is just the opposite of exponentiation, just like dividing is of multiplication.
When asking 'what is 21 divided by 7', you mean 'what number do I multiply 7 with to get 21'.
you have:
y=log%28base+3%29243, then
when asking 'what is 3log243%7B%7B%7B%27%2C+you+mean+%27%7B%7B%7B3 to the power what number equals 243?'
Answer: 3%5E5+=+3%2A3%2A3%2A3%2A3+=+9%2A27+=+243
so, the answer is 5
