Perfect squares have odd numbers of factors. The perfect squares less than 100 are: 1,4,9,16,25,36,49,64,81,100. 64 seems to fit both criteria.

-13 is an odd number which is less than 5.
No, and we doubt that you can either.
There are nine.
It is: 3 plus 97 = 100
There are 9 integers less than 100 that have an odd number of factors.Every factor of a number has a pair, eg 2 & 3 are a factor pair of 6; and so it would be expected that every number has an even number of factors.However, if the factor pair of a number are the same number (eg 6 & 6 are a factor pair of 36), then there will be an odd number of factors.When there is a repeated factor like this, the number is a perfect square.Thus only perfect squares have an odd number of factors.Less than 100 there are 9 perfect squares (1, 4, 9, 16, 25, 36, 49, 64 & 81) which have an odd number of factors.100 itself is a perfect square and also has an odd number of factors, but the question asked for those numbers less than 100 with an odd number of factors.
To find the number of whole numbers less than 100 that are 10 greater than an odd whole number, we can set up an equation. Let x represent the odd whole number. Therefore, the number that is 10 greater than x is x + 10. Since x is odd, it can be represented as 2n + 1, where n is a non-negative integer. Substituting this into the equation x + 10 = 2n + 1 + 10, we get 2n + 11. To find the number of such numbers less than 100, we need to find the largest possible value of n such that 2n + 11 < 100. Solving for n, we get n < 44.5, which means the largest possible integer value for n is 44. Therefore, there are 45 odd whole numbers less than 100 that are 10 greater than an odd whole number.
To find the whole numbers less than 100 that are 10 greater than an odd whole number, we start by identifying the odd whole numbers less than 90 (since 90 + 10 = 100). The odd whole numbers in this range are 1, 3, 5, ..., 89. For each of these odd numbers, adding 10 gives us the corresponding whole numbers: 11, 13, 15, ..., 99. Thus, the whole numbers less than 100 that meet the criteria are all the odd numbers from 11 to 99.
The most factors any odd number less than 100 has is 6. There are 4 numbers which have 6 factors:45, 63, 75 & 99.
