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,lets how the formula that can easily obtain the answer of Square and Square Root.

Square and Square Root using formula

Formula: (a + b)2 = a2 + 2ab + b2
i.e, (a / b)2 = a2 / 2ab / b2 [We replace ‘+’ sign with ‘/’]

We will apply this formula to obtain the square of a Two digit number.

Example #1 – Square and Square Root using Formula

(76)2 = ?

1. 5001
2. 5339
3. 5663
4. 5776

How to Solve

1. Firstly break the number into two parts and Consider a = 7 and b = 6.
2. Applying formula,
a2 + 2ab + b2
OR
a2 / 2ab / b2
= 72 / 2 x 7 x 6 / 62
= 49 / 84 / 36
3. Go from Right to Left
Note down 6 and Carry 3.
4. Add carry 3 with 84,
i.e, (3 + 84) = 87, Note down 7 at the left of 6 and Carry 8.
5. Add carry 8 with 49,
i.e, (8 + 49) = 57, Note down 57 at the left of 7.
So, We get our answer (76)2 = 5776.

How to Solve

1. Firstly break the number into two parts and Consider a = 5 and b = 5.
2. Applying formula,
a2 + 2ab + b2
OR
a2 / 2ab / b2
= 52 / 2 x 5 x 5 / 52
= 25 / 50 / 25
3. Go from Right to Left
Note down 5 and Carry 2.
4. Add carry 2 with 50,
i.e, (2 + 50) = 52, Note down 2 at the left of 5 and Carry 5.
5. Add carry 5 with 25,
i.e, (5 + 25) = 30, Note down 30 at the left of 2.
So, We get our answer (25)2 = 3025.
