Square Root

Who invented this ?

What is it used for ?

Where can you use it?

Why do we need it ?

How do we solve it?

The earliest documentation of who invented the square root was the Rhind Mathematical Papyrus which shows how the Egyptians extracted square roots around 1650 BC. Square root is used for finding a number that to the second power equals the product. We need square root for studying to be a teacher or math professor . It is a little complicated solving square roots but it is possible, a way of solving square root is if you have 7 to the second power it would be 49, therefore the square root of 49 is 7. That way is called guess then solve. A good thing to have for solving square roots is all the square roots from 1-20. This is a list you can use .............

1 to the second power = 1

2 to the second power = 4

3 to the second power = 9

4 to the second power = 16

5 to the second power = 20

6 to the second power = 36

7 to the second power = 49

8 to the second power = 64

9 to the second power = 81

10 to the second power = 100

11 to the second power = 121

12 to the second power = 144
