• Square of a number means multiplying the number by itself 2 times. Remember that 1 has no square number,as you know if we will multiply 1 by itself it will remain same.
• Eg: 2×2= 4
• 10×10= 100 and so on....
• There are 2 identities by which u can find a square of any number. Those identities are

${(a+b)}^{2}= {a}^{2}+{2ab}+{b}^{2}$

${(a-b)}^{2}= {a}^{2}-{2ab}+{b}^{2}$

• Eg Find the square of 103

Sol- (100+3)

By using identity 1

${(a+b)}^{2}= {a}^{2}+{2ab}+{b}^{2}$

${1000+3)}^{2}= {(100)}^{2}+{2}\:100\:time3}+ {3}^{2}$

$= 10000+600+9 = 10609$
