No, it is rational 56/7 = 8 which is rational
No. 5.6 is rational.
No, they are not.
72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.
sqrt(56) = 7.483 approx.
No. The square root of a positive integer can only be an integer, or an irrational number.
Yes - rounded to five decimal places, sqrt(56) = ±7.48331
-56 is a rational number
No, it is rational 56/7 = 8 which is rational
No. 5.6 is rational.
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.
The square root of 3136 is 56.
No, they are not.
72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.
Square root of 56 = Square root of (4 x 14) = (Square root of 4) x (Square root of 14) = 2 x (Square root of 14) The actual value would be 2 x 3.741 = 7.482
2 square root of 14
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
