hmm i'll guide you step by step...add two to both sides
anonymous
  • anonymous
2x^1/3=2
lgbasallote
  • lgbasallote
good! now divide both sides by 2
anonymous
  • anonymous
X^1/3=1
lgbasallote
  • lgbasallote
now take the cube root of both sides...
anonymous
  • anonymous
What exactly doz you mean
lgbasallote
  • lgbasallote
oh wait..i meant cube both sides...you want x..so 1/3 has to cancel out..
anonymous
  • anonymous
So it would just equal. 1
lgbasallote
  • lgbasallote
yes! :DDD

Thankkk youu :)

How about this next problem.. I reallly don't think I got it correct either.. (2x+1)^1/3=1 I got x=0
lgbasallote
  • lgbasallote
get the cube root...then transpose the constant...then divide the constant..you'll get it if you do it step by step ;D

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

  • lgbasallote
yeahhh =)))

Nooo
lgbasallote
  • lgbasallote
ok..cube both sides..ill guide you
anonymous
  • anonymous
I'm beyond confused noww lol...
lgbasallote
  • lgbasallote
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
anonymous
  • anonymous
Sooo 8x^3+1=1
lgbasallote
  • lgbasallote
no no.. when you cube it..the 1/3 gets canceled. 2x-1 = 1 get it?
anonymous
  • anonymous
yes. then you divide 2?
anonymous
  • anonymous
the it will still equal 0
lgbasallote
  • lgbasallote
oh no..2x - 1 = 1 2x = 1 + 1
lgbasallote
  • lgbasallote
oh wait...it's positive??? im sorry you were right
anonymous
  • anonymous
Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh! :D that makes me happy. hahah Thanks for your help! I actually understand :D
