What is a square root

It is quite hard to define it but I believe a square root is a number that can be multiplied by itself to give the original number.

2 x 2 = 4 so the square root of 4 is 2

3 x 3 = 9 so the square root of 9 is 3

So a number which is squared produces another number which can be square rooted to get the original number.

There are many kinds of roots
square root
cube root
4th root
5th root
etc

square=2D so it means 2 identical numbers that multiply to get that number so exg
√4=2 or -2 because 2 times 2=4 and -2 times -2=4

cube root=3 identical number that multiply to get that number exg
∛27=3  or -3 because 3 times 3 times 3=27 and -3 times -3 times 3=27

then 4th root=4 number
5th root=5 numbers and so on

Ican’t sorry i would if i could
