A square root is the number that you multiply twice to get another number. You know, like √2. Square roots are basically squares in reverse.
History[edit | edit source]
It goes back as far as the history of mathematics. You know how 2×2=4, and 9+10=21? That's square roots in disguise!
Examples[edit | edit source]
- √16 is √2 to the fourth power, making it 24 times better. In this case, √16 = 4!
- √10 is objectively the best because there are so many interesting things about it. √10 is close to the mathematical constant π, which means that it's bound to be approximated as such (in fact, Indian mathematicians thought that it equaled π. Remember Protegent?).
Crazy or rational?[edit | edit source]
Well, any whole number that multiplies with itself and transforms into another whole number is a rational square root. Any other number is crazy. Put it in a mental hospital!
Square roots of negative numbers[edit | edit source]
Square roots of negative numbers don't exist. They must be a figment of your imagination.
