Question

Square root 5 x square root 5 x square root 2 x square root 2
Answer left in surds

Answer 1

10 or
`√(100)` (in surds)

Explanation:

`√(5)` ×
`√(5)` ×
`√(2)` ×
`√(2)` = 5×2 = 10 or
`√(100)`

When the same square root multiply each other, they equal to the number in the square root. E.g.
`√(5)` ×
`√(5)` = 5 because
`√(5)` ×
`√(5)` also equals to
`√(25)`, which is 5.

Hope this is helpful :)
