This is a true statement.
Root 7 is an irrational number, and all irrational numbers are real.
Technically, a real number is a number that can be represented as a point on the number line. Root 7= 2.64575.... An example of a number that is not real (imaginary numbers) is Root -1. This is considered to be imaginary and not real because the square of all real numbers is positive.
