The product of two numbers having 0's at the end is calculated by counting the total number of 0's in two numbers. Place the same number of zeros (in both digits) at the end of the product of numbers.
In product of 500 and 6000, there are 2 zeros in 500 and 3 zeros in 6000. So total number of zeros is 2 + 3 = 5.
Evaluate the product of number 5 and 6.
Place five zeros (2 + 3) after the number 30. So product is,
Thus answer is 3000000.
