What is the ones digit of 99?
For the number 25, the 5 is the ones digit (and the 2 is the tens digit). So, for 99 the second 9 from left to right is the ones digit.
What is the value of the digit 9 in 879?
The 9 in 879 represents nine ones or nine units
What is unit digit of 9 to the 20th power?
The units digit of 9n is 9 if n is odd and 1 if n is even. So 1.
What is the ones digit of the following product 159 445 7762 39?
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.
What is the answer to greater than 9 not a multiple of 10 multiple of 7 its odd its not a multiple of 11 its less than 200 its ones digit is larger than its tens digit is tens digit is odd?
35 and 119.
What is the ones digit in 7 to the 50th power?
9
How many two digit numbers are there in which the tens digit is greater then the ones digit?
The answer depends on what the tens digit is greater than, and what the ones digit does then.
What is the one's digit of 7 to the 2015th power Explain the steps you took to reach your answer.?
It is a 3. Look at the ones digit of successive powers of 7; this need only be done by considering the multiplication of the ones digit of the previous power of 7 by 7 (as this is the only calculation that affects the ones digit as each successive power of 7 is the previous power multiplied by 7) and taking the result modulus 10 (to extract the new ones digit as any excess over 9 is carried into the tens column): 7¹ → 7 mod 10 = 7 7² → (7×7) mod 10 = 9 7³ → (9×7) mod 10 = 3 7⁴ → (3×7) mod 10 = 1 7⁵ → (1×7) mod 10 = 7 At this point the pattern of the ones digit will obviously repeat the sequence of the four digits {7, 9, 3, 1}. To find the ones digit of any power of 7, take that power modulus 4 use that digit from the four digit sequence. Note that when taking the number modulus 4, the result will be in the range 0-3; when the result is 0, use the 4th digit from the sequence. 2015 mod 4 = 3 → the third digit of {7, 9, 3, 1}, which is 3, will be the ones digit of 7²⁰¹⁵.
What is the ones digit of 99?
For the number 25, the 5 is the ones digit (and the 2 is the tens digit). So, for 99 the second 9 from left to right is the ones digit.
The number whose ones digit is 8 less than its tens digit . The sum of the digits is a 2 digit number?
91 since the ones digit is 8 less than 9 and the two digits, 9+1 = 10, a two-digit number.
What is the units digit of 9 raised to the 387th power?
9
What is the value of the digit 9 in 879?
The 9 in 879 represents nine ones or nine units
How many two digit number are there in which the tens digit is greater than the ones digit?
If the first digit is 9, you have 9 options (0-8) for the second digit. If the first digit is 8, you have 8 options (0-7) for the second digit. Etc. This leaves you with the arithmetic series: 0 + 1 + 2 + 3 + ... + 9.
What is the units digit of 7 to the 15 power?
Power 2: units digit 9. Multiply by 49 again to get power 4: units digit 1. So every 4th power gives units digit 1. So 16th power has units digit 1, so the previous power, the 15th must have units digit 3.
What are the characteristics of the number 2007?
The composite number 2007 is deficient. Prime factors: 3 * 3 * 223 Prime factors in exponent form: 3^2 * 223 All factors: 1, 3, 9, 223, 669, 2007
How many two-digits numbers are there in which the tens digit is greater than the ones digit?
If the first digit is 9, you have 9 options (0-8) for the second digit. If the first digit is 8, you have 8 options (0-7) for the second digit. Etc. This leaves you with the arithmetic series: 0 + 1 + 2 + 3 + ... + 9.
What is unit digit of 9 to the 20th power?
The units digit of 9n is 9 if n is odd and 1 if n is even. So 1.
