sqrt(225 / 980)
= sqrt(225) / sqrt(980)
= sqrt(3 * 3 * 5 * 5) / sqrt(2 * 2 * 5 * 7 * 7)
= (3 * 5) / (2 * 7 * sqrt(5))
= 15 / (14 * sqrt(5))
Try paying attention in class next time.

Hi,
Well, the simple answer is: .22959….
But I’m guessing that you want an exact answer. So, let’s do it like this:
â (225/980)
= â((5*45)/(5*196)
=â(45/196) (Cancel out the 5s in numerator and denominator.)
=â( 9*5/14²)
= 3â5/14
Hope this helps.
FE

depends if you mean sqrt(225/980) or sqrt(225)/980
the first one would be 15/sqrt980 or (15sqrt245)/2
the second one would be 15/980 or 3/196
have yourself a good day.

sqrt[(225)/980] =
sqrt[(15)^2/(7^2)(2^2)(5) =
15/(7)(2)sqrt(5)=
15/(14)sqrt(5) =
(15) sqrt(5)/14(sqrt(5)(sqrt(5)
(15)sqrt(5)/(14)(5) =
(3)sqrt(5)/14
