Students were inquired to answer a question at institution and to claim what is most important for them to succeed. Of the numerous replies, one that that stood out was practice. Successful people are certainly born successful; they become successful by just hard work and determination. If you want to accomplish your goals, keep this in mind! These are are one of the answer and question example that you will possibly implement to practice and enriches your understanding and also give you insights that would assist you to sustain your study in school.

## Question:

Which numbers are irrational? Select all that apply.

0 9/15

0 v18

0 v9

0 v169

0 v78

0 3.14

## Answer:

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

From the answer and question examples above, hopefully, they can definitely help the student solve the question they had been looking for and notice of all the pieces declared in the answer above. Then would certainly have some sharing in a group discussion and also study with the classmate relevant to the topic, so another student also absorb some enlightenment and still keeps up the school learning.
