Question

solve :-
log(cubic root of 3X-1) + log(cubic root of 3x+1) =log 20-1

Answer 1

\[\log \sqrt[3]{3X-1} + \log \sqrt[3]{3X+1} =\log 20-1\]

Answer 2

emun can do it :)

Answer 3

yeah

Answer 4

give me a minute to finish it

Answer 5

fast plz

Answer 6

i mighta missed it lo

1 , -1

Answer 12

you have to isolate x now

Answer 13

why
U made the power 1/3 to 3

Answer 14

answer me

Answer 15

ahhh ok. Yeah definitively im wrong

Answer 16

gonna try to solve it.

Answer 17

U R welcome

Answer 18

Answer 23

Here you have

Answer 24

wrong

Answer 25

look

Answer 26

Can you realize in what part I mess up?

Answer 27

log 20/10 = log 2

Answer 28

I didt do that anywhere

Answer 29

I dont need that process

Answer 30

sorry
at the end

Answer 31

\[(3X-1)(3X+1) = 8\]

Answer 32

it must be

Answer 33

You are right, but the mistake is at the begining. Gonna try to solve it again

Answer 34

\[9 x ^{2 } + 1 = 8\]

Answer 35

\[9 X ^{2} = 9\]

Answer 36

X = 1 , -1
s.s = {1}

Answer 37

-1 ref..

Answer 38

yeah you were right :)

Answer 39

Hope I was helpful here

Answer 40

U r always

Answer 41

but

Answer 42

but ... too slow

Answer 43

noooooooooooooooo

Answer 44

\[10^{\log20} *10^{-1}\]

Answer 45

or
\[10^{\log20} - 10^{-1}\]

Answer 46

the first one, because \[a ^{m}a ^{n}=a ^{m+n}\]

Answer 47

clear?

Answer 48

ok

Answer 49

can you give me a medal please :) I think I deserve it

Answer 50

but how

Answer 51

^ *cough*

Answer 52

forget something myininaya?

Answer 53

lol the 1
(x-1)(x+1)=0

Answer 54

no, you are saying the solution is x=+-1 , are you sure :P

Answer 55

well its not -1 because we can't have log of negative number

Answer 56

so its just x=1
i was hoping he would know to do that but you are right i should had said that

Answer 57

but I know

Answer 58

this all in my studies
