Question #0a6b8

Answer 1

Find the factors and group them in two sets with the same integers in both sets. The product of either set will be the square root; in this case: `75`.

Explanation:

`sqrt5625`

By a process of simple division, we can determine the factors.

`5625-:5=1125`

`1125-: 5=225`

`225-:5=45`

`45-:5=9`

`9-:3=3`

`3-:3=1`

So we have two sets of factors: `(5xx5xx3)` and `(5xx5xx3)`

The product of either set is `75`, the square root of `5625`.
