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 all square roots rational numbers?
No. Lots of square roots are not rational. Only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.
How many irrational numbers are there between 1 and 6?
There are an infinite number of irrational numbers between 1 and 6. There are all the square roots from 1 to 36 except for 1, 4, 9, 16, 25, and 36. There are all the cube roots between 1 and 216 except for 1, 8, 27, 64, 125, 216. You can calculate fourth roots, fifth roots and continue calculating roots all year long. You should only have your supercomputer calculate irrational roots. Otherwise, you will duplicate. When you have calculated all roots of all prime numbers that fall between one and six, and added in all physical constants, then you will know the answer.
What are rational numbers whose square roots are whole numbers called?
Rational numbers whose square roots are whole numbers are themselves whole numbers. They are called square numbers, e.g. 1, 4, 9, 16, 25 and so on.
Are all square roots irrational numbers?
No. Square root of 9=3. 3=3/1. Therefore not all square roots are irrational
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.
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.
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?
No. For example, the square roots of prime numbers cannot be simplified.
Is the square root of 19 a rational number?
No. 19 is a prime number, and all prime numbers have irrational roots.
Which whole numbers have square roots between 1 and 20?
All whole numbers between 1 and 400 (=20 square).
What square root lies between -7 and -6?
-1
What is the largest prime number that has a square root that is less than 20?
Prime numbers can't have whole number square roots, of course, but the largest prime number under 400 is 397.
Are all square roots of even numbers rational?
No. The square roots 8 are irrational, as are the square roots of most even numbers.
What are the square numbers from 576 to 10000?
The square numbers integers between 576 and 10000 (and their square roots, in the left column) are: 245762562526676277292878429841309003196132102433108934115635122536129637136938144439152140160041168142176443184944193645202546211647220948230449240150250051260152270453280954291655302556313657324958336459348160360061372162384463396964409665422566435667448968462469476170490071504172518473532974547675562576577677592978608479624180640081656182672483688984705685722586739687756988774489792190810091828192846493864994883695902596921697940998960499980110010000
