The square of a number is the number multiplied by itself. Therefore the square of the number 4 written normally as 42 is = 4*4 = 16.
Five more than 42 would therefore be =(4*4)+5 = 21.
x=-3 or x=5
A beprisque number nnn is an integer which is either one more than a prime number and one less than a perfect square, or one more than a square and one less than a prime. The 5th such number is 10.
26 5*5 and 3*3*3
-4.52494 or 5.52494 (to 5 dp)
The smallest square number larger than 20 is 25, which is the square of 5 (5 x 5). Other square numbers larger than 20 include 36 (6 x 6), 49 (7 x 7), and so on.

A prime number that is one more than a square number is known as a Sophie Germain prime. Sophie Germain primes are of the form 2p+1, where p is a prime number. For example, 17 is a Sophie Germain prime because it is one more than the square of 4, and both 4 and 17 are prime numbers. Sophie Germain primes have applications in number theory and cryptography.
