# How do you find the unit digit?

One can easily find the units digit by looking for a pattern. For numbers with large powers, they will have a pattern that keeps repeating like a cycle. Depending on the multiple of the power, the pattern can be compared to find the units digit.

### How do you find the unit digit of 3127 power 173?

The unit digit of 3127173 is the unit digit of 7173. The other digits of 3127 are multiples of 10 and so they cannot contribute to the unit digit. Now the unit digits of the powers of 7 are Power -- Unit digit 0 -- 1 1 -- 7 2 -- 9 3 -- 3 4 -- 1 and you are back into the loop (of 1-7-9-3). So, you only need consider 7 to the…

### What is a unit digit?

A number is made up from digits in the numeral system. We often use the decimal system in which we use 10 digits, In writing the any number, many digits are used, even repitation of digits. when we write any number using the digits, the last digit ( from right side ) in that number is called unit digit. for example in the number 9814868980, here 0 is called unit digit.

### What is nearest whole unit?

To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the tenths place. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn…

### How do you round to the nearest unit?

0-4.99r is the lower unit, 5-9.99r is the higher unit. Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your…

### What is bigger 0.1666666667 or 0.06666666667?

Look for the first digit that is different. In this case, the first digit after the decimal point. The number that has the larger digit in this position, is larger. If the first digit is the same, compare the second digit with the second digit, the third digit with the third digit, and so forth, until you find a difference.

### What is the perimeter of the parallelogram to the nearest whole unit?

The sum total of its sides. To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the tenths place. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is…

### How can you find the 2001st digit of a recurring decimal?

Assume the decimal starts recurring immediately after the decimal point. (If the recurring string starts after k digits, then you want to find the (2001-k)th digit instead.) Find the length of the recurring string = L Find the remainder when 2001 is divided by L = R The 2001st digit is the Rth digit in the recurring string.

### How do you find the surface area of a figure to the nearest square unit?

This is two problems. Surface area is measured in square units. The formulas for the area of different figures vary with the figures. The area of a regular four-sided figure is the length times the width. To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, tenths of square units. If that digit is 4 or lower, zero it and everything to the…
