Topics Covered in Exercise 5.2 Class 8 Mathematics Questions

Exercise 5.2 of NCERT solutions for class 8 maths chapter 5 squares and square roots is about finding the square of a number with other patterns and pythagorean triplets. Detailed explanations of these topics are provided here on eSaral.

1.

Finding the Square of a Number

  • Other patterns in squares

  • Pythagorean triplets

  1. Finding the Square of a Number - In order to figure out the square of any given number, we have to divide the number into two parts, and then we can easily solve it.

               If number is ‘x’ then x = (p + q) and x2 = (p+q)2

The formula (p + q)2 = p2+2pq+q2 can also be used.

  • Other patterns in squares

 Other pattern for the number ending with 5

We can use the pattern for numbers that end with 5. 

(a5)2=a(a + 1)100 + 25

  • Pythagorean triplets

If the sum of two square numbers is also a square number, then these three numbers form a Pythagorean triplet.

For any natural number m > 1, we have (2m)2 + (m2-1)2 = (m2+1)2 . So, 2m, m2-1 and m2+1 forms a Pythagorean triplet.
