simplify

OpenStudy (anonymous):

i know how to simplify the square root of 32 but when i get my answer am i supposed to leave the 3 on the outside the same?

OpenStudy (anonymous):

\[\sqrt[3]{32} = \sqrt[3]{8*4} = 2 * \sqrt[3]{4}\]

OpenStudy (anonymous):

thanks !:) and i have one more

OpenStudy (anonymous):

Just post it.

OpenStudy (anonymous):

\[3\sqrt{56x ^{14}} simplify. and the three in this problem is supposed to be like the three in my previous question(up high)

OpenStudy (anonymous):

\[\sqrt[3]{56x ^{14}}\]

OpenStudy (anonymous):

\[\sqrt[3]{{56x}^{14}} = \sqrt[3]{(7*8)x^{14}} = 2\sqrt[3]{7x^{14}}\]

thanks
