You keep the first digit, replace the remaining digits with zero, and check whether you need to round the first digit up or not.
Since there are only five different digits, a 6-digit number can only be generated if a digit can be repeated. If digits can be repeated, the smallest 6-digit number is 111111.
There is only one three digit number for a gross, and that is 144.
If the number is odd, the last digit is odd. That means the ten's digit must be twice the one's digit. There are only four two-digit numbers where the ten's digit is twice the one's digit: 21, 42, 63, 84. Check which of these satisfy all the clues.
I don't think there is only one number, but, 64 is one. Because: - 8X8 and 4X4X4. Both equal 64
If you don't mind beginning the 4-digit number with one or more zeros, thenthere are 10 choices for each digit, and the total number of possibilities is:(10 x 10 x 10 x 10) = 10,000 .If the 4-digit number can't begin with a zero, then there are only 9 choices forthe first digit, but 10 choices for each of the others, and the total number ofpossibilities is:(9 x 10 x 10 x 10) = 9,000 .
1,000 is the lowest base-10 number that requires 4 significant digits. "0,000" is also a 4-digit number, but the only significant digit is the final zero.
2000 only has one significant digit.
The number whose farthest right significant digit determines it. Whatever place that digit is in is the last significant digit in the sum. For example: 433 + 150 + 3.67 + 8000 = 8586.67, but in sig figs this is only 9000, as the thousands digit is the lowest digit that can be represented.
Five. A number with only five digits, such as 10600, with a non-zero left hand digit (the number 1 in this case) has five significant figures.
Yes, it is by definition a 2 digit number. (At degree level anyway, however at secondary schools you may be taught differently. It depends on what definition your teacher uses). However if you're referring to "significant digits", it has only one significant digit (the 1).
1 The first number has only 1 significant digit, so the answer cannot be more accurate than that.
14 is 125 % of the number 14/1.25 = 11.2, where the digit after the decimal point is depressed because it may not be significant. (The datum 14 has only two significant digits.)
But according to the rules of significant figures, the least number of significant figures in any number of the problem determines the number of significant figures in the answer which, in this case, would be 11.
0.0357 has three significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
3
A one digit number is a number with only one number. For example: 12 is a two digit number. It has two numbers. 3 is a one digit number because it only has one number.
Only three significant digits are correct, because 5.0 contains no digit for hundredths, and such a digit would be required to give four significant digits in the answer. Because 7 + 5 equals exactly 12, a third significant digit is gained for the answer. Note in contrast that the sum of 7.68 and 0.50 would properly contain four significant digits.
