Question
Find the number of zeroes in 16 × 75 × 40 × 125.
Solution
Number of zeros will depend on how many times 10 i.e. (5 × 2) occur in the product Since, 16 × 75 × 40 × 125
= 2 × 2 × 2 × 2 × 3 × 5 × 5 × 2 × 2 × 2 × 5 × 5 × 5 Since, (5 × 2) occurred six times in the given product Therefore, required number of zeros = 6
