How do you solve ln5-3ln2?

Answer 1

it's an expression, so you'll have to use a calculator.

=========================

Right! In this day and age, we've finally reached the point where nobody

knows how to do squat without his machines. Plus ... nobody has a clue

whether the machine has given him the right answer. Beautiful!

ln(5) - 3 ln(2) =

ln(5) - ln(23) =

ln (5/23) = ln (5/8).

Note:

That's not the 'solution' to anything. It's just a different, neater way of writing

the original expression that's in the question. In an algebra class, the answer

doesn't matter. All they really want is for you to learn how to get this far, and

no calculator will tell you that it's ln(5/8).

If your class is so regimented that you need the numerical answer, then you can

go ahead and use the calculator for that:

ln (5/8 ) = -0.47 (rounded)
