Answer:

The correct answer is "it is irrational and equal to 8 square root of 2"

Step-by-step explanation:

x=√50 +√ 18

x=√(25*2) +√(9*2)

By the Radical Properties of Multiplication

x=(√25*√2) + (√9*√2)

x=5√2 +3√2

x=8√2

√2 is a irrational number,  so the right answer is the last option "it is irrational and equal to 8 square root of 2."
