Question

# Determine whether the sum represents a rational number or an **irrational number . Explain how you know without simplifying .**

**The correct answer is: Use the properties of rational and irrational numbers**

**The correct answer is: Use the properties of rational and irrational numbers**

**Complete step by step solution:**

Here one number is rational and the second number is irrational.

So the difference between a rational and irrational number is always irrational.

Hence we can conclude that is an irrational number.
