Hoping you can help! Working on Advanced Algebra....notes aren't helping and I can't remember how to do these problems.
log3 9 + log3 27
instructions are to Express as a single logarithm and simplify if possible!
You can put this solution on YOUR website! log3 9 + log3 27
Adding the logs same as multiplying
log3(9*27) = log3(243); a single logarithm
Exponent equiv of logs
log3(243) = y
3^y - 243
What power of 3 is 243
y = 5
log3(243) = 5
