more problems I can't understand
9^x+2 = 27^-3
I get that 3 will go into both of them but am lost after that, notes don't help
instructions are to solve each exponential equation. Round to 2 decimal places.
and another logarithm
Log (xy^2/Z^4)
Z
edit: Z should be right after/underneath "log" and before the (.

9^x+2 = 27^-3
my bad, problem is 9^x+2 = 27^ -x
I must have been looking two places at once or something. I figured that one out though looking at what you did.
It was in the first section of my notes, one more though
e^5x =77
I have one example dealing with E but it has E on both sides so not sure what to do here. Hopefully this is my last question, thanks for the help.
