none 3 x 3 x 3 = 27 4 x 4 x 4 = 64 ---------------------------- Every number has a cube root, just most of them are not whole numbers, so every number between 30 and 50 is a cube. If you meant what the perfect cube numbers (ie the cubes of whole numbers) between 30 and 50, then the answer is, as above, none.
The square root of 32 approximates to 5.66
30 is an integer and not a fraction. However, it can be expressed in rational form as 30/1.
30 is an integer and not a fraction. However, it can be expressed in rational form as 30/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
If you can completely write a number, using digits, fractions and decimals, then the number is rational. You appear to have accomplished that.
No, it is irrational.
The square root of (any number that isn't a perfect square) is irrational.
No. The square root of 900 is 30, which is most definitely a rational number.
No because the square root of 900 is 30 which is a rational number

The cube root of 27,000 is: 30
30
Cube root of 30 plus 30 times the square root of 3 = 55.29374608
No because it can be expressed as a fraction in the form of 30/1
It is a rational number because it can be expressed as a fraction in the form of 11/30 whereas irrational numbers can't be expressed as fractions
No, only perfect squares like 25 and 36, which are around 30, have a square root that is a rational number.
