Question

I'm trying to figure out what square numbers equal 100 apart from 10? please help me figure this out

Answer 1

`-10`

Explanation:

The only numbers that are the square root of `100` are `10` and `-10`.

We can set up the equation `x^2=100`, to see what numbers equal `100` when you square them.

`x^2=100`

We can take the plus/minus square root of both sides to solve for `x`.

`x=+-10`

`-10` squared and `10` squared are the only solutions to this equation, so they are the only numbers that equal `100` when you square them. If you're still skeptical, try out `9.9999` and `-9.9999` and square them, and you still won't get `100.`
