Find the compounded ratio of the following:
`sqrt 8 : 4 , 3 : sqrt 5` and `sqrt 20 : sqrt 27`
Advertisements
Solution
Compounded ratio of `sqrt 8 : 4 , 3 : sqrt 5` and `sqrt 20 : sqrt 27`
= `sqrt 8/4 xx 3/sqrt 5 xx sqrt 20/sqrt 27`
= `(2 sqrt 2)/4 xx 3/sqrt 5 xx (2 sqrt 5)/(3 sqrt 3)`
= `sqrt 2/sqrt 3`
Compounded raoo = `sqrt 2 : sqrt 3`
