Thread: Logarithm help

I understand the basics, but I can't figure this one out. Any help would be appreciated.

Give the exact answer ( in terms of natural logarithms). Then use a calculator to find an approximat answer.

7.8e^(x/3)ln5 = 14


Thank you for your time.

Thank you for your time.

If you want an exact answer then turn the decimal into a fraction first:


My question, though, is whether the "ln(5)" is part of the exponent, or multiplying the e^(x/3)?

-Dan

It is part of the exponent. Sorry that was not clear.

Thank you for your time.

If the equation is then that's one helluva ugly exact answer .......

Only kidding!! log/log CANNOT BE SIMPLIFIED - engrave (*ahem* metaphorically speaking) this fact on your skull.
