Question

Solve.
2x^1/3-2=0

Answer 1

Igot x=4. But I don't feel that is correct

Answer 2

this is 2x^(1/3) - 2 = 0 yes?

Answer 3

Yes

Answer 4

hmm i'll guide you step by step...add two to both sides

Answer 5

2x^1/3=2

Answer 6

good! now divide both sides by 2

Answer 7

X^1/3=1

Answer 8

now take the cube root of both sides...

Answer 9

What exactly doz you mean

Answer 10

oh wait..i meant cube both sides...you want x..so 1/3 has to cancel out..

Answer 11

So it would just equal. 1

Answer 12

yes! :DDD

Answer 13

Thankkk youu :)

Answer 14

How about this next problem.. I reallly don't think I got it correct either..
(2x+1)^1/3=1
I got x=0

Answer 15

get the cube root...then transpose the constant...then divide the constant..you'll get it if you do it step by step ;D

Answer 16

Lol Si does that mean I got that one wrong to?

Answer 17

yeahhh =)))

Answer 18

Ughhhh

Answer 19

Answer 20

Nooo

Answer 21

ok..cube both sides..ill guide you

Answer 22

I'm beyond confused noww lol...

Answer 23

you have (2x-1)^1/3 = 1 yes? your goal is to get the x on one side only..so you take away the exponent..how? by cubing it :DD now cube

Answer 24

Sooo 8x^3+1=1

Answer 25

no no.. when you cube it..the 1/3 gets canceled.

2x-1 = 1

get it?

Answer 26

yes. then you divide 2?

Answer 27

the it will still equal 0

Answer 28

oh no..2x - 1 = 1

2x = 1 + 1

Answer 29

oh wait...it's positive??? im sorry you were right
