The expression `-8/sqrt 3 - 10/sqrt 14` has to be simplified.
`-8/sqrt 3 - 10/sqrt 14`
= `(-8*sqrt 3)/3 - (10*sqrt 14)/14`
= `(-8*14*sqrt 3 - 10*3*sqrt 14)/(14*3)`
= `(-112*sqrt 3 - 30*sqrt 14)/42`
= `(-56*sqrt 3 - 15*sqrt 14)/21`
The expression` -8/sqrt 3 - 10/sqrt 14 = (-56*sqrt 3 - 15*sqrt 14)/21`
