Yes.
Irrational.
No, it is neither rational nor irrational. It is a complex number.
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
No, an irrational number is, in simple terms, a number that keeps repeating. The square root of 4 is positive or negative 2, which does not repeat and is therefore rational.
Neither. (It is a complex number.)
Irrational.
No, it is not irrational because it is a square root of a negative number - which falls into the set of Complex numbers. Irrational numbers can not have an imaginary component.
The square root of 51 is an irrational number and it is about 7.14128429
It is neither because the square root of -18 is an imaginary number but the square root of 18 is irrational
The square root of negative 36 is an imaginary number and therefore not an irrational number. For a number to be irrational it must first be real.
It's irrational/not a real number
yes; the negative square root of 2 is irrational, for example.
No, it is neither rational nor irrational. It is a complex number.
The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.
The square root of any negative number is not even a 'real' number. It's called 'imaginary', because there's no number you can multiply by itself to get a negative number. The square root of 101 is irrational.
No, an irrational number is, in simple terms, a number that keeps repeating. The square root of 4 is positive or negative 2, which does not repeat and is therefore rational.
Neither. (It is a complex number.)
