What do you do to check whether a number is rational or irrational?

How does finding the square root of a number compare to finding the cube root of a number? Use the number 64 in your explanation.

1. If you're taking square roots, the number must be a perfect square to give a rational root.

64 = 8^2, so β64 = 8 is rational

Similarly, since

64 = 4^3, β64 = 4 is rational.

For small numbers, it's easy to check for possible roots, as there aren't that many candidates. In general, it's much more difficult.

3. for the first one: Irrational Numbers. All numbers that are not rational are considered irrational. An irrational number can be written as a decimal, but not as a fraction. An irrational number has endless non-repeating digits to the right of the decimal point

5. For the 2nd question:

Square is number which we get after multiply a number x to itself where as cube is a number which we get after multiplying a number x to itself three times. To find the square root or cube root of any number just right it using prime factorization method .
