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):

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
