What is the unit digit of 6?
So, the cyclicity of 3 has 4 different numbers 3, 9, 7, 1. 7 and 8 follow similar logic. So these four digits i.e. 2, 3, 7 and 8 have a unit digit cyclicity of four steps….Cyclicity Table.
| Number | Cyclicity | Power Cycle |
|---|---|---|
| 6 | 1 | 6 |
| 7 | 4 | 7, 9, 3, 1 |
| 8 | 4 | 8, 4, 2, 6 |
| 9 | 2 | 9, 1 |
How do you find the unit digit?
Units digit of a number is the digit in the one’s place of the number. i.e It is the rightmost digit of the number. For example, the units digit of 243 is 3, the units digit of 39 is 9.
What is the unit digit of number 13 14 15?
Hence remainder is 0. Hence the unit digit of 13^14^15^16 is 1.
What is the unit digit in 6 59?
From 6^59, we will only get 6 as the units digit. From 7^71, we will get 7^(68 + 3), ie 3rd term of the cycle, ie 3. So effectively the units digit of the expression is the units digit of the number 3*6*3, which is 4. (as the number is 54).
What is the unit digit in 365 * 659 * 771?
What is the unit digit in the product (365 x 659 x 771)? Unit digit in 74 ⟹ Unit digit in (74)17 is 1. ∴ Required digit = Unit digit in (3 x 6 x 3) = 4. 1.
What is the unit digit in 71057?
So, the required unit digit will be the unit digit of 71. This will be 7.
What is the unit digit of the given number?
So unit digit of the given number is 6 Solution: Here The unit place having ” 1″ so the final number is also comes ” 1″ as a unit place Hint: The last digit of any number having “9” then power having even number then unit place comes 1 and power having odd number then unit place comes 9
What is the last digit of power of 1 5 and 6?
The last digit of power of 1, 5 & 6 is always comes same number as a unit place. If the unit place ( Last digit ) of any number “ An ” having 2, 3, 7 or 8, then the unit place of that number depends upon the value of power “ n” and follows
What is the digit of (7 925 x 3 158) = 27?
Hence the last digit will be 9. Therefore, unit’s digit of (7 925 X 3 158) is unit’s digit of product of digit at unit’s place of 7 925 and 3 158 = 3 * 9 = 27. Hence option 1 is the answer.
How do you find the unit place of a number?
If the unit place ( Last digit ) of any number “ An ” having 2, 3, 7 or 8, then the unit place of that number depends upon the value of power “ n” and follows If the unit place ( Last digit ) of any number “ An ” having 4 & 9 then the unit place of that number depends upon the value of power “ n” and follows
