Simplify Completley

OpenStudy (anonymous):

\[\sqrt{18y ^{10}}\]

OpenStudy (anonymous):

Simplify completely

OpenStudy (whpalmer4):

can you factor 18?

OpenStudy (anonymous):

18 = 9 * 2

OpenStudy (anonymous):

so yes you can

OpenStudy (whpalmer4):

What is 18/1? What is 18/2? What is 18/3? What is 18/6? What is 18/9? Are there any other numbers which divide evenly into 18?

OpenStudy (anonymous):

yes

OpenStudy (whpalmer4):

what other numbers divide 18 and leave no remainder?

OpenStudy (anonymous):

6

OpenStudy (whpalmer4):

I believe that is the 4th line of my list... anyhow: 18 = 2*3*3 \[\sqrt{18} = \sqrt{2*3*3}\]Can you simplify that at all?

OpenStudy (whpalmer4):

Hint: Remember that \[\sqrt{a*a} = a\]

OpenStudy (anonymous):

A. \[3y ^{5\sqrt{2}}\] B. \[3y ^{4\sqrt{2y}}\] C. \[3y ^{5\sqrt{3}}\] D. \[6y ^{5}\]

OpenStudy (anonymous):

A.

OpenStudy (tkhunny):

Too bad \(\sqrt{y^{10}} = \left|y^{5}\right|\)

OpenStudy (whpalmer4):

sloppy problem writing taking it for granted that \(y>0\)

OpenStudy (anonymous):

\[3\sqrt{2}\left| y ^{5} \right|\]
