125^1/3 evaluate? But how?

OpenStudy (lgbasallote):

racing to 1/3 means taking the cube root

OpenStudy (anonymous):

by that you mean doing 125 ^3???? lol

OpenStudy (lgbasallote):

raising i mean...darn those word problems i did earlier

OpenStudy (lgbasallote):

and no 125^3 is cube...cube root is this \[\huge \sqrt[3]{125}\]

OpenStudy (anonymous):

haha no worries... ive been doing an entire chapter today! My brain aches! Ohhh I knew that... thank you (:

OpenStudy (lgbasallote):

welcome

OpenStudy (anonymous):

5?

OpenStudy (anonymous):

and what about if its 2/3 instead of 1/3?

OpenStudy (lgbasallote):

then that means you take the cube root first, then square it

OpenStudy (lgbasallote):

this is a general rule you can remember: \[\huge a^{m/n} \implies \sqrt[n]{a^m}\]

OpenStudy (anonymous):

OHHHHH Oh my gosh you rock :)

OpenStudy (anonymous):

25?

OpenStudy (lgbasallote):

yes 125^(2/3) is 25

OpenStudy (anonymous):
