6 is the only perfect digit. The next perfect number is 28.
Yes, except for the number 1, which is a perfect square but not composite.
0. 0 is a perfect square as well as a perfect cube. And 011 = 0. The next number will be 1.
64 = 82 and 43 1 = 1^2 and 1^3 0=0^2 and 0^3
Almost perfect numbers refer to numbers whereσ(x) = 2x - 1, where σ is the sum of divisors function. Any number in the form 2n is almost perfect becauseσ(2n) = 1 + 2 + 4 + ... + 2n = 2n+1-1 = 2(2n) - 1.It is unknown whether any other almost perfect numbers exist.
0, 1 and 64 are three numbers that qualify.
The two perfect numbers between 1 and 30 are: 6, 28
only the number 1 (one)because it is perfect nth root .
There are infinitely many such numbers. For example, any irrational number between 0 and 1. The principal square root of any number between 0 and 1 which is not a ratio of perfect squares. Such a number will have infinitely many digits, and lie between 0 and 1.

64 = 82 and 43 1 = 1^2 and 1^3 0=0^2 and 0^3
There is an infinite amount of numbers between 0 and 1 on the number line.
The median numbers are 1 and 0. This is because there is no middle number.
If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.
There are an almost infinite number of real numbers between 0 and 1.
Answer 144 which is F(12) Reason 55 and 89 are the 10th and 11th Fibonacci numbers, If we add these we have 144 which is the 12 Fibonacci number and is a perfect square. I am using F(0) as the 0 Fibonacci number and F(1) as the first.
