Question

Identify the number as rational or irrational. Explain. Type your answers below.

-√127

Answer 1

I'm not sure how to do this.

Answer 2

Rational numbers can be written as a fraction (like a ratio)
Irrational numbers cannot be written as a fraction.

Unless the square root of \(-\sqrt{127}\) is a perfect square, then it is irrational.

Answer 3

So, −√127 would be an irrational number?

Answer 4

For example,
\(\sqrt{4}\) is a rational number because the square root is equal to 2.
\(\sqrt{6}\) is an irrational number thus it needs to be simply left as \(\sqrt{6}\) (unless the direction asks for any approximations).

Answer 5

Yes that is correct.

Answer 6

Alright thank you. you cleared that up for me.

Answer 7

No problem :)
