(remember, when jenny multiplies the square root of her favorite integer by sqrt(2), she gets an integer.)

Part a)

Part b) When Jenny divides the square root of her favorite positive integer by , she gets an integer

Step-by-step explanation:

Let

x-------> the favorite positive integer

Part a)

1) For

-----> the product is an integer

so

The number could be Jenny favorite positive integer

2) For

-----> the product is an integer

so

The number could be Jenny favorite positive integer

3) For

-----> the product is an integer

so

The number could be Jenny favorite positive integer

Part B)

1) For

-----> the result is an integer

2) For

-----> the result is an integer

3) For

-----> the result is an integer

Therefore

When Jenny divides the square root of her favorite positive integer by , she gets an integer
