\[\large 2\sqrt[3]{108}\] What are the factors of 108?

OpenStudy (kamibug):

1,2,3,4,6,9,12,18,27,36,54,108

OpenStudy (kropot72):

The cube root of one of those factors is an integer. Can you find that factor?

OpenStudy (kamibug):

27?

OpenStudy (kropot72):

Correct. 4 * 27 = 108. Now we can take 27 outside the radical sign, remembering to take its cube root as we do. Can you do that?

OpenStudy (kamibug):

\[3\sqrt[3]{4}\]

OpenStudy (kamibug):

I would multiply 3 by 2 and get D, right?

OpenStudy (kropot72):

Correct. Good work!

OpenStudy (kamibug):

Thank you! :D
