Submit Answer

Answer 1

Explanation:

`(2)/(√(40) )`

=
`(2)/(√(40) )*(√(40) )/(√(40) )` multiply root on top and bottom

=
`(2√(40) )/(40)` reduce fraction outside of root

=
`(√(40) )/(20)` break up 40 under root

=
`(√(4*10) )/(20)` break up roots to see better

=
`(√(4)√(10) )/(20)` √4 = 2

=
`(2√(10) )/(20)` reduce fraction outside of root

=
`(√(10) )/(10)` answer
