What is the unit digit in the product (381 x 542 x 613 x 874)?A] 1                             B] 3                             C] 7                 D] 4

To find the unit digit in the product of multiple numbers, you only need to multiply the unit digits of each number together.

Here are the steps:

1. Identify the unit digit of each number: 381 is 1, 542 is 2, 613 is 3, and 874 is 4.
2. Multiply these digits together: 1 x 2 x 3 x 4 = 24.
3. The unit digit of the product is the same as the unit digit of this result. So, the unit digit of the product (381 x 542 x 613 x 874) is 4.

So, the answer is D] 4.

To find the unit digit in the product of multiple numbers, you only need to multiply the unit digits of each number together.

Here are the steps:

1. Identify the unit digit of each number:

   • The unit digit of 381 is 1.
   • The unit digit of 542 is 2.
   • The unit digit of 613 is 3.
   • The unit digit of 874 is 4.

2. Multiply these unit digits together:

   • 1 x 2 x 3 x 4 = 24
