$x ^{3}=\frac{ 1 }{ 8 }$ ?

solve for the cube roots both sides

@Marc1313 remember to use ^ to indicate exponential. Example, 3^x to mean $$3^x$$

okY SO HOW DO I SOLVE IT

10. anonymous

sorry how do i solve it?

11. anonymous

i know the answer is 1/2

12. anonymous

but i dont know which one

13. anonymous

$\sqrt[3]{x ^{3}}=\sqrt[3]{\frac{ 1 }{ 8 }}$ $x^{3/3}=\frac{ 1 }{ 8 }^{1/3}$ $x ^{1}=1/2$ $x=1/2$

im not sure but i think we get $\pm 1/2$ IF we get the SQUARE root of the value: 1/8 @mathmate is it 1/2 or $\pm 1/2$? :)

i want to get the answer right and im not sure @KarlaKalurky

hints: $$\Large (\frac{1}{2})^3=?$$ $$\Large (-\frac{1}{2})^3=?$$
