Final answer:
The irrational numbers in the given options are √10 and √99.
Step-by-step explanation:
The irrational numbers are numbers that cannot be expressed as a fraction or in the form of a terminating or repeating decimal. To determine which numbers in the given list are irrational, we need to check if their square roots are irrational.
Out of the options listed, √10 and √99 are irrational numbers. This is because their square roots cannot be simplified and result in non-repeating decimals.
Therefore, the correct responses are a. √10 and e. √99.
