Question 7 Write two numbers whose product is 10000. The two numbers should not have 0 as the units digit.To do this, we do prime factorisation of 10,000 ∴ 10,000 = 2 × 2 × 2 × 2 × 5 × 5 × 5 × 5 = 24 × 54 Now, to get two numbers without 0 as the units digit We need to avoid multiplying 2 × 5 Thus, 10,000 = 24 × 54 = 16 × 625 So, required two numbers are 16 and 625
