As all competitive exams are very tightly bound with time, we discuss the using formula and how we get the result of square and square root of near base 100 using formula, lets how the formula that can easily obtain the answer of Square and Square Root of 100 base.

### Square and Square Root shortcut tricks

Now we can use the above method that is 100 base method when the number is near about 100 we apply this method.

let see the example of 100 base method.

Some we can not remember square of 100 base number that my very heard to remember here the less effort is require to remember those square numbers.

### Example #1 – Square and Square Root of 100 base

(98)^{2} = ?

- 8642
- 9604
- 10472
- 12845

**Answer:**Option (B)

**How to Solve**

- Subtract 98 from 100,

i.e, (100 – 98) = 2. - Then square the result,

i.e, 2^{2}= 4. Note down 4. - As the square is a single digit number so we Add an extra Zero to the left of 4,

i.e, 04. - Now subtract the difference value (2) from the number,

i.e, (98 – 2) = 96. Note down 96 to the left of 04.

So, we get our final result (98)^{2}= 9604.

**Answer:**Option (C)

**How to Solve**

- Subtract 96 from 100,

i.e, (100 – 96) = 4. - Then square the result,

i.e, 4^{2}= 16. Note down 16. - Now subtract the difference value (4) from the number,

i.e, (96 – 4) = 92. Note down 92 to the left of 16.

So, we get our final result (96)^{2}= 9216.

i want some more shortcut tricks on square roots

do you want more square shortcut (a+b)SQUARE =asquare + 2xaxb + bsquare as 108 square = a=100,b=8

1 square x10000+8x1x2x100 +8 square =64 =11664

321 square= 3 square x 10000 + 21x2x3x100+ 21square= 90000+12600+441=103041

(a-b)SQUARE =asquare – 2xaxb+bsquare as 96 square = a=100 b= 4

How will we find out 54 square by using 100 bases method ?

We can find square of 54 using 50 base

54- 50 = 4

add 4 to the 25 ie 29

square of 4 is 16

so answer is 2916

100 base method is long so you can find the answer with 50 base method .

The formula is (25plus minus D) D square 00

D= Difference

00 means, there will be 2 digit at last

Now solve the problem …

54-50 = 4, D= 4

D square = 16 (16 is a 2 digit number, if there will be a 1 digit number than we add a 0 before them )

Now 25+4 = 29

29 and 16 write as 2916, ans..

This mothod solve my problem but this trick take more time

We can find square of 54 using 50 base.

54-50 =4

add 4 to 25 ie 29

square of 4 is 16

so answer is 2916
