Answer: The answer is 0.
Step-by-step explanation: We are given to find the unit digit in the product of first 30 even natural numbers.
The first 30 even natural numbers are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60.
To find the unit digit, we do not need to evaluate the total product, but since the unit digit in 5 numbers, that are 10, 20, 30, 40, 50 and 60 is 0, so the total product must have unit digit 0.
Thus, the answer is 0.
