Question
Show the conjecture is false by finding a counterexample. The square root of any positive integer x is always less than x.
Hint:
Inductive Reasoning is the process of drawing a general conclusion by observing a pattern based on the observations and this conclusion is called conjecture.
Counterexample: It is an example which shows that the conjecture is false.
The correct answer is: Hence, the counterexample for the given conjecture is the number “0.01”.
Let’s take the square root of 4, 9 and 16
We can see that the square root of the assumed positive number is less than the number.
But if we take 0.001. Its square root is
= 0.1
0.1 is greater than 0.01. So, the given conjecture is wrong as the square root of 0.01 is not less than 0.01
Final Answer:
Hence, the counterexample for the given conjecture is the number “0.01”.
