Im completely lost as how to do some of these
log2 of 2x+log2 of x+5
7^2x-4=14
3e^x+7=9
log3 of x+log3^(x-6)=3
log4 (5x-2)=3
Expanding confuses me too
log3 of (7x^2/y)
One of condensing too
log2 of 7 +log2 of x - 3log2 of y

what are the instructions for this?

is the 4 in the power, or not? (for solving go here)
clintator wrote:3e^x+7=9
is the 7 in the power, or not?

log4 (5x-2)=3
they have a lesson here for solving log eqns
