Answer:
Prime factorisation is a method to find the prime factors of a given number, say a composite number. These factors are nothing but the prime numbers. A prime number is a number which has only two factors, i.e. 1 and the number itself.
Find the square root of 9604 by the prime factorisation method
We have to find the square root of 9604 by the prime factorisation method
9604 = 2 × 2 × 7 × 7 × 7 × 7× 1
9604 = (2 × 2) × (7 × 7) × (7 × 7)
9604 = (2 × 7 × 7) × (2 × 7 ×7)
9604 = (2 × 7 × 7)2
Therefore, √9604 = 2 × 7 × 7 = 98.
