If: x2 = 81 Then: x = 9 or x = -9
81
Factors are just numbers 81 can be divided by. The whole number factors are 1, 3, 9, 27, and 81
The factors of 81 are 1, 3, 9, 27, 81. For them to be common, they need to be compared to another set of factors.
1, 3, 9, 27, 81 81 27,3 9,3,3 3,3,3,3
If: x2 = 81 Then: x = 9 or x = -9
If a, b, c, and d are positive integers that add up to 20 they each must be less than 20. If abcd=81 then a, b, c, and d must be factors of 81. The factors of 81 are 1,3,9 then 27, so there is no solution to this problem.
81 is a composite number because it has more than two factors.
81
71 is a prime number because it has only two factors whereas 81 is a composite number because it has more than two factors.
The factors of 18 are 1,2,3,6,9, and 18. The factors of 81 are 1,3,9,27, and 81.
16 and 81 are the only two.
The factors of 81 are: 1 3 9 27 81
The factors of 81 are 1, 3, 9, 27, and 81.
It has more than two distinct factors; they are 1, 3, 9, 27, 81
How about: 79+81 = 180 as one example
The factors of 81 are 1, 3, 9, 27, and 81.
