Find the following please include how you got that as well please :)

OpenStudy (anonymous):

\[\sqrt{16k ^{8}}\]

OpenStudy (kropot72):

\[\sqrt{16k ^{8}}=\sqrt{16}\times \sqrt{k ^{8}}\] Do you know what the square roots of 16 and k^8 are?

OpenStudy (anonymous):

4 for 16

OpenStudy (kropot72):

When finding the square root of k^8 use the rule \[\sqrt{a ^{b}}=a ^{\frac{b}{2}}\]

OpenStudy (anonymous):

and when ever it's an indicy do I divide it by 2 if its square root

OpenStudy (anonymous):

ohh i see so its \[\sqrt{4k ^{4}}\]

OpenStudy (kropot72):

You are on the right track but you don't need the radical sign: \[\sqrt{16k ^{8}}=4k ^{4}\]

OpenStudy (anonymous):

oh woops

OpenStudy (anonymous):
