show me your work...

Answer 7

ln3x=2?

Answer 8

Yes you are right...

Answer 9

good, now what?

Answer 10

Take antilog both the sides:

\[3x = Antilog(2)\]

Answer 11

is the answer 7?

Answer 12

sorry i meant 4

Answer 13

What is antilog (2) i don't know..

Answer 14

I dont know myself

Answer 15

\[Antilog(2) = 7.39\]

Divide it by 3 and you wll get x..

Answer 16

What are the options ??

Answer 17

2.46

Answer 18

Yes I got the same ..

Answer 19

Thank You so much, I'm almost done... log 3 5 + log 3 x = log 3 10 can you help me with this one?

Answer 20

Use:

\[\log(a) + \log(b) = \log(ab)\]

Answer 21

\[\large \log_3(5x) = \log_3(10)\]

Now logs are same so the terms inside will be equal:

\[5x = 10\]

find x from here..

Answer 22

Nice now can you just check this one for me? 22n = 16-, i said the solution is -2

Answer 23

22n = 16 ??

Answer 24

22n = 16^-1 ....sorry

Answer 25

no sorry again its 2^2n=16^-1

Answer 26

\[\large 2^{2n} = 16^{-1} \implies 2^{2n} = 2^{-4}\]

\[2n = -4\]

\(n = -2\)

Answer 27

Yes you are right..
