New Question!
(3x^1/3)-1=5

Answer 1

Are you looking to solve for X?

Answer 2

if solving for... x=8

Answer 3

\[{3}^{1/3}-1=5\]

Answer 4

How?

Answer 5

3 x^(1/3)-1 = 5
Isolate terms with x to the left hand side.
Add 1 to both sides:
3 x^(1/3) = 6
Divide both sides by a constant to simplify the equation.
Divide both sides by 3:
x^(1/3) = 2
Eliminate the cube root on the left hand side.
Raise both sides to the power of three:
then u ll get x = 8

Answer 6

I see. I suppose I just couldn't figure out how to cube root on my TI-84...
I'll have to look that up

Answer 7

^ (3)

Answer 8

You will see the " ^ " button on the middle right side above the division symbol.

Answer 9

right, but that won't help me cube root, will it?

Answer 10

Cube yes but the cube root is actually " ^(1/3) "

Answer 11

\[\sqrt[3]{x} = x ^{1/3}\]

Answer 12

\[\sqrt[3]{x} = x^{\frac{ 1 }{ 3 }}\]

Answer 13

So you can use that button to solve for the cube root or any other root as well.

Answer 14

Nice @Johnbc, how did you get it to do the x^1/3 like that?

Answer 15

so, i'm down to x^1/3= 2, and I eliminate the ^1/3 how on my calculator?

Answer 16

Last bar on the right side and last image as well. @Cosmichaotic

Answer 17

Oh duh. Thank you much @Johnbc

Answer 18

Well you need to perform algebra first and take the cube of both sides which is " ^ (3) "

Answer 19

My pleasure.
