The correct question is;

Which numbers are irrational? Select all that apply.

A) 9/15

B) √18

C) √9

D) √169

E) √78

F) π = 3.14 ...

Answer:

The irrational numbers are;

√18; √78 and π = 3.14 ...

Step-by-step explanation:

An irrational number is a number that cannot be written as the ratio of two integers. Its decimal form does not stop and does not repeat.

Thus;

A) 9/15 = 0.6 It's decimal stops after 6 and thus it is not irrational

B) √18 = 4.242640687119285 ... The decimal doesn't repeat and the continuous dots means it's decimal doesn't stop. Thus it is an irrational number

C) √9 = 3. Doesn't have a repeating or continuous decimal and thus it's not irrational

D) √169 = 13. Doesn't have a repeating or continuous decimal and thus it's not irrational

E) √78 = 8.831760866327846 ...

The decimal doesn't repeat and the continuous dots means it's decimal doesn't stop. Thus it is an irrational number

F) π = 3.14 ... The continuous dots means it's decimal doesn't stop. The decimal doesn't repeat and so, it's an irrational function
