Rationalise the denominator of the following
`sqrt2/sqrt5`
Advertisements
उत्तर
We know that rationalization factor for `1/sqrta ` is `sqrta`. We willmultiply numerator and denominator of the given expression `sqrt2/sqrt5` by `sqrt5`, to get
`sqrt2/sqrt5 xx sqrt5/sqrt5 = (sqrt2 xx sqrt5)/(sqrt5 xx sqrt5)`
`= sqrt10/5`
Hence the given expression is simplified to `sqrt10/5`

Rationalise the denominator of the following:
`(4sqrt(3) + 5sqrt(2))/(sqrt(48) + sqrt(18))`
Rationalise the denominator in the following and hence evaluate by taking `sqrt(2) = 1.414, sqrt(3) = 1.732` and `sqrt(5) = 2.236`, upto three places of decimal.
`1/(sqrt(3) + sqrt(2))`
If `sqrt(2) = 1.414, sqrt(3) = 1.732`, then find the value of `4/(3sqrt(3) - 2sqrt(2)) + 3/(3sqrt(3) + 2sqrt(2))`.
