What is the result of multiplying two irrational numbers?

Prime
Whole
Rational
Irrational

The correct answer is: Irrational

Two irrational numbers when multiplied can result in a rational number or an irrational number. However, it is more likely that the result will be an irrational number. The options of "Prime", "Whole", and "Rational" are incorrect because prime numbers are only divisible by 1 and themselves, whole numbers are integers without a fractional component, and rational numbers are numbers that can be written as a fraction of two integers. An irrational number is any number that cannot be expressed as a fraction of two integers, and this is the most likely result when multiplying two irrational numbers. Therefore, the correct answer is "D Irrational".
