To find the units digit of 8 to the power of 50, we need to look for a pattern in the units digits of powers of 8. The units digit of powers of 8 cycles in a pattern: 8^1 = 8, 8^2 = 4, 8^3 = 2, 8^4 = 6, and so on. Since the cycle repeats every 4 powers, we can divide 50 by 4 to find that the 50th power will have the same units digit as 8^2, which is 4. Therefore, the units digit of 8 to the power of 50 is 4.

How many possibilities are there with the four digit numbers 0000-9999 while the first number cannot be 0 or 9?
The first digit can be any one of 8. For each of these . . .The second digit can be any one of 10. For each of these . . .The third digit can be any one of 10. For each of these . . .The fourth digit can be any one of 8.Total possibilities = (8 x 10 x 10 x 8) = 6,400
What is an 8 digit number called?

How many three-digit whole numbers have no 7's and no 9's as digits?
The first digit can be one of {1, 2, 3, 4, 5, 6, 8}, ie one of 7 digits; for each of these, the second digit can be one of {0, 1, 2, 3, 4, 5, 6, 8}, ie one of 8 digits; for each of these two, the third digit can also be one of {0, 1, 2, 3, 4, 5, 6, 8}, ie one of 8 digits; making 7 × 8 × 8 = 488 such three digit numbers.
How can you use the digit 8 four times to make 89?
88 + 8/888 + 8/8 = 89

What is the units digit of 8 to the power of 19?
819 = 144115188075855872 The number in the units column is therefore 2.
What is the units digits of 8 to the power of 50?
It is 2.
What is the unit’s digit in the expansion of 2 raised to 725?
The unit's digit in the expansion of 2 raised to the 725th power is 8. This can be determined by using the concept of the "unit's digit law". This law states that the units digit of a number raised to any power is the same as the units digit of the number itself. In this case, the number is 2, which has a units digit of 2, so the units digit of 2 to the 725th power is also 2. However, this is not the final answer. To get the unit's digit of 2 to the 725th power, we must use the "repeating pattern law". This law states that when a number is raised to any power, the unit's digit will follow a repeating pattern. For 2, this pattern is 8, 4, 2, 6. This means that the units digit of 2 to any power will follow this pattern, repeating every 4 powers. So, if we look at the 725th power of 2, we can see that it is in the 4th cycle of this repeating pattern. This means that the units digit of 2 to the 725th power is 8.
What is the units digit of 2 to the 48th power?
Expressed in numerical form, 248 = 281474976710656 - the units digit is therefore 6. With the exception of 20 = 1. the units digit of successive powers of 2 runs 2, 4, 8, 6... continuously - therefore, an exponent which is a multiple of 4 will have a units digit of 6.
What is the units digit of 2 to the power of 2011?
To find the units digit of a number raised to a power, we can look for patterns in the units digits of the powers of that number. For 2, the units digits of the powers cycle in a pattern: 2, 4, 8, 6. Since 2011 is 3 more than a multiple of 4 (2011 = 4 * 502 + 3), the units digit of 2 to the power of 2011 will be the fourth number in the cycle, which is 6.
What is the units digit of 248?
It is 8.
What is the value of the digit 8 in 68?
8 units
What value will the units digit of the number 20082008 be?
8 : the units digit is the first digit to the left of the decimal point if you had to write one in.
What is the units digit of 2 to the 57th power?
Well, darling, to find the units digit of 2 to the 57th power, you just need to look for a pattern. The units digit of powers of 2 cycles every 4 powers: 2, 4, 8, 6. So, 57 divided by 4 leaves a remainder of 1, meaning the units digit of 2 to the 57th power is 2. Hope that clears things up for you, sugar!
When is a number a multiple of 4?
When the tens digit is even and the units digit is 0, 4 or 8 or the tens digit is odd and the units digit is 2 or 6.
How many 2-digit integers greater than 50 have the property that the sum of the digits is more than double the units digit?
When the units digit equals the tens digit then the sum of the digits of a 2 digit number is double the units digit. In each tens range above 50, numbers below this critical point meet the requirement, numbers above this critical point have a sum LESS than double the units digit. The applicable numbers are 51-54 (4), 61-65 (5), 71-76 (6), 81-87 (7) and 91-98 (8). Then there are 4 + 5 + 6 + 7 + 8 = 30 qualifying numbers.
What is the units digit of 2 to the 725th power?
Look at the first few powers of 2: 2, 4, 8, 16, 32, 64, 128, 256,512, 1024, 2048The units digit repeats every four: [ 2 - 4 - 8 - 6 ] - [ 2 - 4 - 8 - 6 ] - etc.725/4 = 181 with remainder of 1 .So if you raise 2 to the 725th power, the units digit completes the whole4-step cycle [ 2-4-8-6 ] 181 times, and then advances one more step ... to 2 .
