-56 is a rational number

An irrational number is a number that cannot be expressed as a/b. a and b must both be integers. With 56, this can be expressed as 56/1. As both 56 and 1 are integers, 56 is a rational number. All whole numbers are rational.

No, it is rational 56/7 = 8 which is rational

It is an irrational number and it is about 7.483314774

Yes - rounded to five decimal places, sqrt(56) = ±7.48331

No. The square root of a positive integer can only be an integer, or an irrational number.

It is an irrational number and it is 2 times the square root of 14. It is approximately 7.4833.

72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.

None of them because they are all rational numbers but 19 is a prime number.

The question could ask for the perfect cube of 56, which equals 563 = 175616. However, it can also mean to ask whether 56 can be a cube, which could be answered by 56(1/3), which cubed is 56. Since 56(1/3) is an irrational number, it is impossible to construct this perfectly, but one can make arbitrary precise approximations, close to 3.825862365...
