Question

best way to learn root and square

Answer 1

Step-by-step explanation:

Dear friend math is fun.. and here I am going to tell some really easy ways to learn the squares

First learn upto 10 squares.. and honestly speaking if you know the tables, learning the first 10 would be really easy.

Squares From 02 to 62

0 Squared = 0 × 0 = 0

1 Squared = 1 × 1 = 1

2 Squared = 2 × 2 = 4

3 Squared = 3 × 3 = 9

4 Squared = 4 × 4 = 16

5 Squared = 5 × 5 = 25

6 Squared = 6 x 6 = 36

7 Squared = 7 x 7 = 49

and so on...

then learn upto 20( they are little hard but remember practice makes a person better )

When we square a negative number we get a positive result.

Just the same as squaring a positive number:

5x5 = -5 x -5

Square Roots

A square root goes the other way:

square root of 9 is 3

3 squared is 9, so a square root of 9 is 3

A square root of a number is ...

... a value that can be multiplied by itself to give the original number.

A square root of 9 is ...

... 3, because when 3 is multiplied by itself we get 9.

and so on

Now look up to the images..they are quite helpful for finding squares of big numbers with 2-3 secs

Hope this helps..THANK YOU
