Which description does not apply to -sqrt(9)?

Question

A - Real number

b- whole number

c- integer

d- rational number

Answer 1

The negative square root of 9 results in -3.

The hierarchy of real numbers is as follows

Real- Rational numbers, integers, whole numbers, and natural numbers.

Rational- any number that can be represented as a fraction

Integer- negative and positive numbers and zero.

Whole- numbers from 0 and above

Natural- numbers from 1 and above

Based on our answer of -3, it is not considered a whole number since whole numbers range from zero to any non-decimal positive number.

Answer 2

-√9 = -3, which is real, rational, and an integer, but is NOT a whole number
