What square numbers below 100 are also prime numbers?
A [perfect] square number, by definition, has a factor which is its square root. As a result it CANNOT be a prime!
Is there any prime numbers that are square numbers?
No, there are no prime numbers that are also square numbers. Prime numbers are only divisible by 1 and themselves, while square numbers have integer square roots. Since the square root of a prime number is not an integer, a prime number cannot be a square number.
What real number is also irrational?
All real numbers are irrational. For example, Pi is an irrational number that is a real number. Other irrational numbers can be the square root of an imperfect square.
Why can there not be a prime number that is also a square number?
Square numbers, greater than 1, have more than two factors.
When you subtract one square number from another square number the answer is 35 what are the two numbers?
The likely square numbers are 36 and 1. (6^2 - 1^2) However, the square numbers 324 and 289 also work. (18^2 - 17^2)

How many triangular numbers are also square numbers?
There are an many triangular numbers that are also square numbers. Simply put, the sum of two consecutive triangular number equals a square number. Examples include 1 and 36.
Is there any prime numbers that are square numbers?
No, there are no prime numbers that are also square numbers. Prime numbers are only divisible by 1 and themselves, while square numbers have integer square roots. Since the square root of a prime number is not an integer, a prime number cannot be a square number.
Can you explain why some square numbers are odd numbers?
The square of any odd number is also an odd number for reasons that should be obvious.
What is the smallest square number that is the sum of two square numbersfind two squares numbers whose sum is a square number?
25 is a square number, and the sum of 9 and 16 is 25. 9 and 16 are also square numbers.
Are all square numbers also composite numbers explain?
Every square number (except 1) is composite. Prime numbers only have two factors, one and the numbers themselves. Since square numbers also have at least the square roots as factors, they have to be composite.
Are square numbers also prime numbers?
Absolutely not. A square number has an integer square root, so by definition it has at least one factor. Prime numbers have no factors
Are they any other square numbers of 4?
4 is a square number in its own right and 4*4 = 16 which is also a square number
What real number is also irrational?

What is a rational number whose square root is a whole number?
If the square root is a whole number, then the square of the square root, the original number, is also a whole number; all whole numbers can be expressed as themselves over 1, and so are rational numbers. The answer is thus any square number, ie the square of the natural numbers: 1 (1²), 4 (2²), 9 (3²), 16 (4²), etc.
