i know it's pretty simple to solve - but i can't find anything in my book about it and i know i have a test tomorrow over it any help?
Break it down to simpler forms. You know e^ln(x) = x so try to make something of that form.
5e^3(ln(6))= 5e^(ln(6^3)). Move the in front of the ln to be the power of the 6.
Then we know that e^ln(x) = x, so
5e^(ln(6^3)) = 5 (6^3) = 5(27)(64) = 320(27) = (300+20)(27) = 8100+ 540 = 8640.
i figured it out and i'm glad for the help but that's the wrong answer. you were close.
the way i did it to find the answer(i have the answer sheet so it helps a lot)
5e^ln216 6^3 = 216 - i think that's where u got it wrong
e and ln cancel out
5 * 216 = 1080
again thanks for the help, i might be posting some other stuff in this area later tonight - midterms etc...
