Yes, -81 is an integer. An integer is a whole number that can be positive, negative, or zero. In this case, -81 is a negative whole number, making it an integer.
82 is not the square of an integer. The closest square number of an integer is 81, which is equal to 9 squared.
Techcially all numbers are divisible by 81, however many would result in a decimal answer. If you mean how many numbers are divisible by 81 and have an integer answer, then it is "all multiples of 81" - e.g 81 x 2, 81 x 3 etc...81, 162, 243 and keep adding 81 forever.
its 81
8145 is an integer and so it is in its simplest form.
81 is a multiple of 3.
Yes, 81 is an integer. Integers are whole numbers that can be positive, negative, or zero, and 81 falls into the category of positive integers.
The largest factor of any positive integer is the number itself.
The positive integer factors of 81 are:1, 3, 9, 27, 81

105
The only common positive integer factor of 35 and 81 is 1.
Yes, but the result won't be an integer.
82 is not the square of an integer. The closest square number of an integer is 81, which is equal to 9 squared.
Integer, rational, and real.
9, 3, 27. that's it.
Yes, it is 9.Yes and it is 9
25/81 is the simplest form: The prime factors of 25 are only 5, and those of 81 are only 3. Therefore, no integer other than 1 can divide both numbers to product an integer result.
