Question

Solving Exponential Equations Help?

Answer 1

OK, so to solve you are going to take the natural log of both sides

Answer 2

How do I do that?

Answer 3

ln 7 = ln 27.09
Divide both sides by ln 7
ln 7/ln 7 = ln 27.09/ln 7

Answer 4

1=1.70

Answer 5

your answer would be approx 1.70

Answer 6

do you understand how I got that?

Answer 7

Yes:)

Answer 8

One second I'm going to try another one and send it to you to see if I'm right...

Answer 9

I have no idea how to do this one....

Answer 10

it is similar to the last problem you had so you take the natural log of 5.5 and round your answer

Answer 11

.89?

Answer 12

that is not what I got... it is approximately 1.70

Answer 13

did you put in your calculator ln(5.5) since that is what you are trying to solve?

Answer 14

Okay I pushed enter after..

Answer 15

what did you get?

Answer 16

The .89

Answer 17

@Johnbc

Answer 18

You would need to do the opposite of \[e^x\] to both sides

Answer 19

So divide?

Answer 20

Opposite of that would be \[Ln\] so take the natural log of both sides
