What are examples of irrational numbers?

An example is the square root of a number. Ex: square root of 2. This is 1 example, not the main one. Any cube root or square root which doesn't give a perfect number is an irrational number. Ex; square root and cube root of 5, since their answer will be 2.24 and 1.70 which are not perfect numbers like square roots of 25 and 64 or cube roots of 27 and 216.

A perfect number is one whose positive integer factors, other than itself, add up to the number itself. For example, the factors of 6, other than itself, are 1, 2, 3, and 1 + 2 + 3 = 6. Therefore, 6 is a perfect number.The first eight perfect numbers are:62849681283355033685898690561374386913282305843008139952128

Why is 16 a near perfect number?

A near-perfect number is one that is close to being a perfect one (obvi). So to find out if it's perfect or not (there are other terms, but that doesn't really matter right now), you add up it's divisors other than itself. So for example: 6 is a perfect number because 1+2+3+6. 16 1+2+4+8=15, so thus it is near-perfect. The four perfect numbers are 6, 28, 496, 8128

Is 75 perfect abundant or deficient?

A perfect number is one with factors (apart from itself) that sum to give the original number. An abundant number is one where this sum is greater than the original number. A deficient number is one where the sum is less than the original number. The factors of 75 are 1, 3, 5, 15 and 25. The sum of these numbers is 49. Thus 75 is a deficient number.
