Question

`√(2) / 2 + 2 / √(2 )`
What does it equal to?? ​

Answer 1

`(3√(2) )/(2)`

Explanation:

Given

`(√(2) )/(2)` +
`(2)/(√(2) )` ← rationalise the denominator by multiplying by
`(√(2) )/(√(2) )`

=
`(√(2) )/(2)` + (
`(2)/(√(2) )` ×
`(√(2) )/(√(2) )` )

=
`(√(2) )/(2)` +
`(2√(2) )/(2)`

=
`(3√(2) )/(2)`
