Let's call our number <em>x</em>.
So we can setup the equation x² = 100.
To solve this equation, we square root both sides.
So we have x = ±10.
Always use plus or minus when square rooting both sides
of an equation so our answer is not only 10, it's also -10.
A^2+b^2=C^2
=
4+144=148
The square root of 148 is 12.165
round it down to 12

=2(7n+10)(7n−10)
Answer:
2(7n+10)(7n−10)
This is not a terminating decimal because 70/800 can be 0.0875.
