Question

5 root 12 + 4 root 12 - 3 root 18 +2root 75​

Answer 1

Answer: 28
`√(3)` - 9
`√(2)`

Explanation:

5
`√(12)` + 4
`√(12)` - 3
`√(18)` + 2
`√(75)`

5
`√(12)` + 4
`√(12)` can be added together since they have the same radical, they will be treated as if you have 5 apples + 4 apples , which will be 9 apples

Therefore we have

9
`√(12)` - 3
`√(18)` + 2
`√(75)`

`√(12)` =
`√(4)` X
`√(3)` = 2
`√(3)`

`√(18)` =
`√(9)` X
`√(2)` = 3
`√(2)`

`√(75)` =
`√(25)` X
`√(3)` = 5
`√(3)`

Returning them back into the expression , we have

9(2
`√(3)`) - 3(3
`√(2)`) + 2 (5
`√(3)`)

⇒ 18
`√(3)` - 9
`√(2)` + 10
`√(3)`

= 28
`√(3)` - 9
`√(2)`
