Question

Can a radical ever be rational? Glve examples. Justify your answer using complete sentences.

Answer 1

Answer:

Yes

Step-by-step explanation:

Yes, a radical can be a rational, this is because a radical indicates the square root of a number. An example of this is $\sqrt{25}$ = 5.

Answer 2

Answer: Yes.

Step-by-step explanation:

A radical is a number of the shape √x, and a rational is a number of the shape a/b, where x, a and b are integer numbers.

Now, particularly, you have 2 = 12/6 for example so 2 is a rational number.

And you also have that 2*2 = 2^2 = 4

so √4 = 2.

Then we have that 2 is a radical and a rational number.
