We can therefore write the function rule:
Answer:
gives rational solution and
gives an irrational solution.
Step-by-step explanation:
We are given the numbers 5 , 8 , 24.
Using these numbers and maximum four operations given, we need to find the problem having a rational and irrational solution.
Now, applying two operations namely division and squaring, we define the following problem having a rational solution.
i.e. =
=
= 9, being an integer, it is a rational number.
Further, applying only one operation namely square root, we define the problem having an irrational solution.
i.e. , which is an irrational number.
Hence, the problems gives a rational solution and
gives an irrational solution.
