No. Sqrt(-4) contains a radical but it not irrational; it is imaginary.
Yes.
√ 5 is an irrational number. Any square root of a prime number is irrational.
No, 40 is a rational number.
No, they are not.
No. Sqrt(-4) contains a radical but it not irrational; it is imaginary.
Yes.
The square root (radical) of 5 is about 2.2361 (an irrational number)
√ 5 is an irrational number. Any square root of a prime number is irrational.
No. Radical(1.21) = 1.1, for example, is rational.
The root of an irrational doesn't have any specific name - radical pi is just radical pi, for example.
No, 40 is a rational number.
If the symbol preceding the 61 is intended to be a radical sign, the answer is yes. If it is not a radical, it depends on the value of v.
No, they are not.
no, because the root of a number that isn't a perfect square is irrational
The square root of 40 is an irrational number
40 is a rational number, so the question is misguided.
