Answer:

see explanation

Explanation:

using the rules of radicals


√(a) ×
√(b)
√(ab)


\sqrt{(a)/(b) }
(√(a) )/(√(b) )

(1)


√(108)

=
√(36(3))

=
√(36) ×
√(3)

= 6
√(3)

(2)


√(14) ×
√(35)

=
√(14(35))

=
√(490)

=
√(49(10))

=
√(49) ×
√(10)

= 7
√(10)

(3)


\sqrt{(28)/(64) }

=
(28)/(√(64) )

=
(√(28) )/(8)

=
(√(4(7)) )/(8)

=
(√(4)(√(7)) )/(8)

=
(2√(7) )/(8)

=
(√(7) )/(4)
