Question

How do i answer this please?

Answer 1

a)
`5√(3) + 3√(5)`

b)
`4(√(2) + √(7))`

Explanation:

a)
`9√(3) - 4√(3) +√(5) + 2√(5)`

Taking √3 & √5 common respectively,

`=> √(3) (9 - 4) + √(5) (1 + 2)`

`=> 5√(3) + 3√(5)`

b)
`10√(2) + 4√(7) - 6√(2)`

Taking √2 common ,

`=> √(2) (10-6) + 4√(7)`

`=> 4√(2) + 4√(7)`

Taking 4 common ,

`=> 4(√(2) + √(7))`
