Hint: For solving this question first we will see the definition of rational and irrational numbers. Then, we can answer this question correctly without any doubt.

Complete step by step answer:
Given:
We have to tell whether (π227) is rational or irrational or its value is zero.
First, we should know the definition of rational and irrational numbers.
For a number to be rational when we express a number in the form of pq , where p,q are integers such that q0 . For example: 2,43 and any integer are rational numbers. But when any number cannot be expressed in such form then, that number will be irrational. For example: π,e,2 are irrational numbers. Few properties related to rational and irrational numbers are as follows:
1. Product of a rational and irrational number is an irrational number
2. Sum and difference of a rational and irrational number is always an irrational number
3. Division of any rational and irrational number is always an irrational number
Now, we came back to our question of whether (π227) is rational or irrational or its value is zero.
As we know that, 227 is a rational number and π is an irrational number. Then, according to the second property we can say that, (π227) will be an irrational number.
Thus, (π227) is an irrational number.


Note: Here, chances of making one mistake is very high and that is to answer zero directly because usually we take π=227 , but we should know that 227 is not the exact value of π and π is an irrational number.
