What's the cube root of 125? Do you know?

OpenStudy (anonymous):

the cube root of 27 is 3 and the cube root for 125 is 5

hero (hero):

I see. so x = 5/3

OpenStudy (anonymous):

hero (hero):

Go ahead. Maybe there's an equivalent value

OpenStudy (anonymous):

ok

hero (hero):

5/3 can be expressed in more than one form. You have to keep that in mind as well.

hero (hero):

Sometimes, with multiple choice, the answer isn't given literally.

OpenStudy (anonymous):

a. 25/9 b.plus or minus 25/9 c. 5/3 d.plus or minus 5/3

OpenStudy (anonymous):
