    So that means that B is rational then right?

    The numbers 8 and 2 are rational because they can be expressed as fractions: 8/1 and 2/1. Irrational numbers cannot.

    Good. We are ready to answer the question. A) square root of 64 plus square root of 5 = 8 + square root of 5 The whole thing is irrational if any part of the sum is irrational. B) square root of 64 plus square root of 4 = 8 + 2 = 10. 10 is a rational number because it can be written as the ratio of two integers: 10/1. So, Option B represenets a rational number.

    So that means the A is irrational, but B is rational, henceforth it is D right?

    Correct: A is irrational, but B is rational.
