It might be rational according to the technical definition of 'rational',
but it's imaginary.
The square root of 16 is ±4 which is the rational number ±(4/1)
A negative square root is not rational because it is typically represented as an imaginary number. For example, the square root of a negative number, such as -1, is expressed as "i," where i is the imaginary unit. Rational numbers are defined as numbers that can be expressed as the quotient of two integers, and imaginary numbers do not fit this definition. Thus, negative square roots are not considered rational.
The negative square root of 100 is -10. Since -10 can be expressed as a fraction (-10/1), it is considered a rational number. Thus, the negative square root of 100 is rational.
No, it is a complex number.
yes
The square of a negative number is always positive. The square of -8 = 64, a rational number
The square root of 16 is ±4 which is the rational number ±(4/1)
Every positive rational number and its negative are the two square roots of the same positive rational number.
Yes, it is.
The square root of 100 is rational since it is not repeating. No. The square root of a negative number is not a real number, but an imaginary number, because no real number squared equals a negative number. The square root of a negative number is a so-called IMAGINARY number
The negative square root of 100 is -10. Since -10 can be expressed as a fraction (-10/1), it is considered a rational number. Thus, the negative square root of 100 is rational.
One over sixteen = 1/16, which is a rational number (not irrational). The square root of 1/16 = 1/4 (or -1/4), which is also a rational, so the answer is No.
Yes.
No, it is a complex number.
yes
The square root of 100 is rational since it is not repeating.
It is a rational number because it can be expressed as an improper fraction in the form of -80/1
