Thus, the last digit of 7295 is equal to the last digit of 73 i.e. 3. Let’s divide 158 by 4, the remainder is 2. Hence the last digit will be 9. Therefore, unit’s digit of (7925 X 3158) is unit’s digit of product of digit at unit’s place of 7925 and 3158 = 3 * 9 = 27.
What is the unit digit in the product 7 153?
Question 20. (1) Þ units digit of 7153 = that of 71 = 7.
What is the unit digit of 7 7 7?
I simply multiply 7*7 = 49 take the last digit 9 and multiply by 7 again gives me 9*7 = 63 from this take the last digit gives me 3. Hence the unit digit of 7^7^7 is 3.
When 7 126 is multiplied out what is the digit in the ones place?
7^2 has a 9 in the ones place, so 7^126 should also have a 9 in the ones place.
What is the unit digit of 122 173?
By dividing 173 by 4, we get 1 as a remainder. So, unit’s place digit in (122)173 = 21 = 2.
What is the unit digit of the expression 317 171?

What is the unit digit in the product 264 102?
∴ Unit digit in (264)100 is also 6. Therefore, the unit digit in (264)102 + (264)103 is 6 + 4 = 10 i.e. 0.
What is the units digit of 7?
1. Digits 0, 1, 5 & 6: When we observe the behaviour of these digits, they all have the same unit’s digit as the number itself when raised to any power, i.e. 0^n = 0, 1^n =1, 5^n = 5, 6^n = 6….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 |
What is the units digit of 33 408?
The pattern in the units digit is 3, 9, 7, 1, 3, 9, . . . . The pattern will continue to repeat with every four integers of the exponent. Dividing 408 by 4 yields 102 with no remainder. Therefore, the units digit of 33408 will be the same as the units digit of 334, which is 1.
What is the last digit of 7 Power 100?
so the last digit of 7100 is 1.
What is the unit digit in 27 power 20?
Answer is “1”
What is the unit digit of (3127)^173?
The unit digit of a power is determined by the corresponding powers of the unit digit. Now the powers of the unit digit 7 are 7, 9, 3, 1, 7, 9…. Hence 7^4 has 1 as its unit digit. Now 173 = 43×4 + 1. Therefore the unit digit of (3127)^173 = [{(3127)^4}^43]×(3127) is 1×7 = 7.
How do you find the unit digit of 7^4?
The unit digit of a power is determined by the corresponding powers of the unit digit. Now the powers of the unit digit 7 are 7, 9, 3, 1, 7, 9…. Hence 7^4 has 1 as its unit digit.
What is the unit digit of 7153?
(3547) 153 x (251) 72 In (3547) 153, unit digit is 7. The cyclicity of 7 is 4. Dividing 153 by 4, we get 1 as remainder. So, the unit digit of 7153 is 7. In 251 72, unit digit is 1. Because 1 has the cyclicity 1, the unit digit of 251 72 is 1. (3547)153 x (251)72 is 7.
What is the unit digit of (3547)153 x (251)72?
Cyclicity of 10 is 1. Find the unit digit in the product : (3547) 153 x (251) 72 In (3547) 153, unit digit is 7. The cyclicity of 7 is 4. Dividing 153 by 4, we get 1 as remainder. So, the unit digit of 7153 is 7. In 251 72, unit digit is 1. Because 1 has the cyclicity 1, the unit digit of 251 72 is 1. (3547)153 x (251)72 is 7.
