root2/10 is the answer
sqrt(50)=5*sqrt(2) ==> 1/sqrt(50)=1/(5*sqrt(2))
multiply and divide by sqrt(2)
==> {1/[5*sqrt(2)]}*[sqrt(2)/sqrt(2)]
==> [1*sqrt(2)]/[5*sqrt(2)*sqrt(2)]
==> sqrt(2)/[5*[(sqrt(2))^2]]
==> sqrt(2)/[5*2]
==> sqrt(2)/10
1/sqrt(50)=sqrt(2)/10
sqrt(50)=5*sqrt(2) ==> 1/sqrt(50)=1/(5*sqrt(2))
multiply and divide by sqrt(2)
==> {1/[5*sqrt(2)]}*[sqrt(2)/sqrt(2)]
==> [1*sqrt(2)]/[5*sqrt(2)*sqrt(2)]
==> sqrt(2)/[5*[(sqrt(2))^2]]
==> sqrt(2)/[5*2]
==> sqrt(2)/10
1/sqrt(50)=sqrt(2)/10
