and method

Answer 17

no i did it in my head.. and i got B

Answer 18

yes and this is how it works \[3^{2x} = 5 \]
apply power rule \[\huge\rm 2x~ \ln 3 = \ln 5\]
divide both side by ln3 \[2x =\frac{ \ln ~5 }{ \ln3 }\]
and then divide by 2

Answer 19

then you are too smart you don't need to ask if it is right or not
bec you know it's correct :-)

Answer 20

no @Nnesha IM KIDDING M NOT ACTUALLY THAT SMARTTTTTT

Answer 21

Answer 27

divide both side by ln3 \[2x =\frac{ \ln ~5 }{ \ln3 }\]
and then divide by 2
use calculator ln 5 divide by ln 3 = ?

Answer 28

one sec

Answer 29

I got this: 0.73248676

Answer 30

by dividing ln 5 and ln 3 = .732486 ?? :-)

Answer 31

yes

Answer 32

did u not get that?

Answer 33

nope
well that's mean you didn't divide ln 5 over ln 3

Answer 34

i know how it is
that's what i got from ln(5)/ln(3) https://www.google.com/?gws_rd=ssl#q=calculator+

Answer 35

write ln(5) / ln(3)

Answer 36

1.51539

Answer 37

divide by 2

Answer 38

0.75769504

Answer 39

\[2x =\frac{ \ln ~5 }{ \ln3 }\]

\[2x = 1.46497352072\]
ln5/ln 3 = 1.46497352072
and then divide by 2 you would get ur answer :-)

Answer 40

0.73248676

Answer 41

right

Answer 42
