Answer:


(7√(5) )/(8)

Explanation:

Using the rules of radicals


\sqrt{(a)/(b) } =
(√(a) )/(√(b) )


√(a) ×
√(b)
√(ab)

Given


\sqrt{(245)/(64) } =
(√(245) )/(√(64) )

Simplifying the radicals


√(245)

=
√(5(7)(7))

=
√(49(5))

=
√(49) ×
√(5) = 7
√(5)

and


√(64) = 8

The simplified radical is


(7√(5) )/(8)
