Can every square root be simplified?
No. For example, the square roots of prime numbers cannot be simplified.
What is prime with cube roots?
All numbers have cube roots (not necessarily integral cube roots) so every prime has cube roots.
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 are prime numbers with square roots between 4 and 5?
The prime numbers with square roots between 4 and 5 are 5 and 7.
What are digital roots of prime numbers?
To find the digital root of a number, repeatedly add its digits (called "digit sum") until you're left with a 1-digit number, 1 thru 9; e.g., 19 (a prime number) = 1+9 = 10 = 1+0 = 1, i.e., the digital root of 19 is 1 [sometimes expressed as 19=dr(1)]. Here's one more example, 89 (a prime) = 8+9 = 17 = 1+7 = dr(8).
Why are the square roots of prime numbers greater than one always rational?
They aren't. The square roots of prime numbers are always irrational.
Can every square root be simplified?

How do you know that 59 and 89 are prime numbers?
59 and 89 are prime numbers because they have exactly two factors, 1 and the number itself. Another test is that they are not evenly divisible by 2, 3, 5, or 7, which are the only prime numbers smaller than their square roots.
What is the square root of 50 turned into fraction?
The square roots of 50 are irrational numbers. You cannot turn irrational numbers into fractions, which are rational numbers.
Why is the calculator important?
Without it you wouldn't be able to find the square roots of prime numbers.
What are the compex roots in mathematics?
The complex roots of an equation is any solution to that equation which cannot be expressed in terms of real numbers. For example, the equation 0 = x² + 5 does not have any solution in real numbers. But in complex numbers, it has solutions.
