When multiplying numbers with the same units digit, the units digit of the product is determined by the units digit of the base number raised to the power of the number of times it is being multiplied. In this case, since 7 is being multiplied 100 times, the units digit of the product will be the same as the units digit of 7^100. The units digit of 7^100 can be found by looking for a pattern in the units digits of powers of 7: 7^1 = 7, 7^2 = 49, 7^3 = 343, 7^4 = 2401, and so on. The pattern repeats every 4 powers, so the units digit of 7^100 will be the same as 7^4, which is 1. Therefore, the units digit of the product when one hundred 7's are multiplied is 1.
It is the unit's digit of the product of the unit's digits. For example, the units digit of 123456 * 4689 is simply the units digit of 6*9 = 54, which is 4.
7100 = (74)25 As 74 = 7 x 7 x 7 x 7 = 2401 and the units digit of this number is 1 then multiplying this number by itself 25 times would still leave a 1 in the units place. The answer to your question is 1.
The product of 64 multiplied by 9 is 576. This can be calculated by multiplying the two numbers together using the standard multiplication algorithm, where you multiply the units digit of the two numbers, then the tens digit, and so on, carrying over any remainders as needed. In this case, 64 multiplied by 9 results in 576.
To find the last but one digit in the product of the first 75 even natural numbers, we need to consider the units digit of each number. Since we are multiplying even numbers, the product will end in 0. Therefore, the last but one digit (tens digit) will depend on the multiplication of the tens digits of the numbers. The tens digit will be determined by the pattern of the tens digits of the even numbers being multiplied.
Find the units digit of 8*7. The 30 in 38 will have no effect on the units digit.
It is the unit's digit of the product of the unit's digits. For example, the units digit of 123456 * 4689 is simply the units digit of 6*9 = 54, which is 4.
The units digit of 159*445*7762*39 is the units digit of the product of the units digits of the four numbers, that is, the units digit of 9*5*2*9 Since there is a 5 and a 2 in that, the units digit is 0.
7100 = (74)25 As 74 = 7 x 7 x 7 x 7 = 2401 and the units digit of this number is 1 then multiplying this number by itself 25 times would still leave a 1 in the units place. The answer to your question is 1.
0 Look at the product of the first 3 prime numbers: 2 x 3 x 5 = 30. Any number multiplied by 30 will have a 0 in the units digit. So, no matter how many prime numbers you are multiplying, if once you have a number ending in 0, all of the rest will end in 0.
The product of 64 multiplied by 9 is 576. This can be calculated by multiplying the two numbers together using the standard multiplication algorithm, where you multiply the units digit of the two numbers, then the tens digit, and so on, carrying over any remainders as needed. In this case, 64 multiplied by 9 results in 576.

Either hundred thousands or units (ones).

The last digit in the product of the first 20 odd natural numbers can be determined by looking at the pattern of the units digit in the multiplication of consecutive odd numbers. The units digit of the product of consecutive odd numbers alternates between 1 and 5. Since there are 10 odd numbers between 1 and 19, and 20 is also an odd number, the last digit in the product of the first 20 odd natural numbers is 5.
10 You can only have one choice, the number 4 as the hundred digit and also one choice, the number 5 as the units digit. However, you can have any integer from 0-9 as the hundreds digit. The number of combinations is thus 1 x 10 x 1 = 10.
The units digit of a whole number is always the rightmost digit.
