Sam said the square root of a rational number must be a rational number. Jenna disagreed. She said that it is possible that the
2 answers:
Answer: Jenna is correct.
Step-by-step explanation:
We can prove this statement with help of two examples.
Since we know that 64 is the rational number.
And, the square root of 64 is .
Which is equal to 8 or -8.
And, they are integers, and we know that the integer are always a rational number.
Therefore is a rational number.
And, If we take a number 2 which is a rational number.
Since, when we do square root of 2, we get √2.
And, √2 is a irrational number.
Thus, we can say that we can obtain a rational or irrational number after doing the square root of rational number.
Therefore, Jenna is correct.

Answer:
Step-by-step explanation:
For this exercise it is important to remember the multiplication of signs. Notice that:
In this case you have the following expression given in the exercise:
Then you can follow the steps shown below in order to solve it:
Step 1: You must solve the subtraction of the numbers 0,65 and 3,21. Then:
Step 2: Now you must find the product of the decimal numbers above. In order to do that you must multiply the numbers.
(As you can notice, both are negative, therefore you know that the product will be positive).
Then, you get that the result is the following:
