No. 5.6 is rational.
No, it is rational 56/7 = 8 which is rational
Yes, -56 is a real number. Real numbers include all the rational and irrational numbers, and -56 is a rational number because it can be expressed as a fraction, specifically -56/1. It is also located on the number line, which is a characteristic of real numbers.
72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.
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...
yes
No
No, it is rational 56/7 = 8 which is rational
-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.
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.
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.

56 is a rational whole natural number. Or to put it another way: 56 is a Natural number, but as all natural numbers are also whole numbers 56 is also a whole number, but as all whole numbers are also rational numbers 56 is also a rational number. Natural numbers are a [proper] subset of whole numbers; Whole numbers are a [proper] subset of rational numbers. The set of rational numbers along with the set of irrational numbers make up the set of real numbers
Irrational. Irrational. Irrational. Irrational.
