Find the square root of the expression (1)/(xyz) (x^(2) + y^(2) + z^(2)) + 2((1)/(x) + (1)/(y) + (1)/(z))

Answer»

`(x + y + z)/(xyz)`
`sqrt((yz)/(x)) + sqrt((zx)/(y)) + sqrt((XY)/(z))`
`sqrtx + sqrty + sqrtz`
`sqrt((x)/(yz)) + sqrt((y)/(xz)) + sqrt((z)/(xy))`

Solution :(i) Use ALGEBRAIC identities to factorize the given POLYNOMIAL
(II) Multiply the first three terms with xyz
(III) Now express the expression in `(a +b +c)^(2)` form
