No, it is an imaginary number which is a complex number.
Yes, the square root of negative 4.2 is considered an irrational number because it involves the square root of a negative value, which results in an imaginary number. Specifically, the square root of negative 4.2 can be expressed as (i\sqrt{4.2}), where (i) is the imaginary unit. Since (\sqrt{4.2}) is an irrational number, the entire expression remains irrational.
Irrational.
Yes.
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.

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.
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.
No, the square root of an irrational number is not always rational. In fact, the square root of an irrational number is typically also irrational. For example, the square root of 2, which is an irrational number, is itself irrational. However, there are exceptions, such as the square root of a perfect square of an irrational number, which can be rational.
