It's not totally clear whether you mean SQR(5) / 3 or SQR(5/3), which would be two different things. Either way, though, chances are the answer your math teacher or book is going for isn't a decimal. "Properties of radicals" implies that you should write your answer in simple radical form. That means you shouldn't have any root on the bottom of a fraction, and you should have the smallest possible number under the root.

SQR(5) / 3 would already be in simple radical form.

To simplify SQR(5/3), first break it down into two roots.
SQR(5) / SQR(3)
Then mulfiply by SQR(3) / SQR(3) ... the bottom over itself.
SQR(15) / SQR(9)
Simplify the root on the bottom
SQR(15) / 3
Since you can't simplify the square root of 15, the answer is considered to be in simple radical form.

go on your website and consider the "web page source" such as your browser. (correct click on your first web page and scroll to "view web page source" or "view source") you've more effective than one header which works to confuse the hell out of the Google crawlers. also, the header containing the Google verification code is in a unmarried header that comes decrease than the body tag. restoration your HTML so that you've in basic terms one header till now the body tags and be particular Google's verification is nice inserted. Take out all that unnecessary more effective meta tag junk. It became in all likelihood generated by technique of be conscious Press. .

radical(5/3)= radical5/radical 3 = (radical5Xradical3)/radical 3Xradical 3= (radical 15/ 3) =3.67/3 =1.29 ans.
