C.π (pi)
D.√10/49

Answer 1

The numbers 3.14, π (pi), and the square root of 10/49 are irrational numbers.

Step-by-step explanation:

An irrational number is a number that cannot be expressed as a fraction, and its decimal representation goes on forever without repeating. The irrational numbers among the given options are:

• A. 3.14: This is the decimal representation of the irrational number π (pi).
• C. π (pi): π is an irrational number as its decimal representation goes on forever without repeating.
• D. √10/49: The square root of 10/49 is an irrational number because the square root of a non-perfect square is always irrational.

Therefore, the correct options are A, C, and D.
