Riya marks five numbers in her notebook: 7/2, √8, 0.6 (terminating), π, and 0.121121112... (with one more 1 each time, non-recurring). She wants to count how many of these are irrational. What is that count?

Question

Accepted Answer

3. √8 = 2√2 is irrational, π is irrational, and 0.121121112... is non-terminating non-recurring so irrational. 7/2 and 0.6 are rational. Hence 3 irrationals.
