To determine the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888, we can use the Prime Number Theorem. This theorem states that the density of prime numbers around a large number n is approximately 1/ln(n). Therefore, the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888 can be estimated by dividing ln(8888888888888888888888888888888888888888888888) by ln(2), which gives approximately 1.33 x 10^27 prime numbers.
They are: 83, 89 and 97
The only prime numbers between 81 and 90 is... 83
83
They are: 79+2 = 81
Three: 83, 89, 97

It must be 81 because 9 squared is 81 and 9 is not a prime number whereas the other numbers are squared prime numbers.
