**CBSE Class 8 Revision Notes Maths Squares and Square Roots**

**Square**: Number obtained when a number is multiplied by itself. It is the number raised to the power 2. 2^{2}= 2 x 2=4(square of 2 is 4).- If a natural number m can be expressed as n
^{2}, where n is also a natural number, then m is a**square number.** - All square numbers end with 0, 1, 4, 5, 6 or 9 at unit’s place.
- Square numbers can only have even number of zeros at the end.
- Square root is the inverse operation of square.
- There are two integral square roots of a perfect square number.
- Positive square root of a number is denoted by the symbol
^{2}=9 gives , For example, 3 **Perfect Square or Square number**: It is the square of some natural number. If m=n^{2}, then m is a perfect square number where m and n are natural numbers. Example: 1=1 x 1=12, 4=2 x 2=2^{2}.**Properties of Square number**:

(i) A number ending in 2, 3, 7 or 8 is never a perfect square. Example: 152, 1028, 6593 etc.

(ii) A number ending in 0, 1, 4, 5, 6 or 9 may not necessarily be a square number. Example: 20, 31, 24, etc.

(iii) Square of even numbers are even. Example: 2^{2}= 4, 4^{2}=16 etc.

(iv) Square of odd numbers are odd. Example: 5^{2}= 25, 9^{2}= 81, etc.

(v) A number ending in an odd number of zeroes cannot be a perferct square. Example: 10, 1000, 900000, etc.

(vi) The difference of squares of two consecutive natural number is equal to their sum. (n + 1)^{2}– n^{2}= n+1+n. Example: 4^{2}– 3^{2}=4 + 3=7. 12^{2}– 11^{2}=12+11 =23, etc.

(vii) A triplet (m, n, p) of three natural numbers m, n and p is called Pythagorean triplet, if m^{2}+ n^{2}= p^{2}: 3^{2}+ 4^{2}= 25 = 5^{2}
