Let a represent a non-zero rational number and let b represent an irrational number
Which expression could represent a rational number?
a + b
It somewhat depends on what the irrational number is.
If it is something simple such as √3,
then the expression that would represent a rational number would be:
(√3)² would be 3…..which is a rational number.
All the other choices would still remain irrational numbers.
Best Answer: b²
