Write the statement in if-then form:
the product of two even integers is an even integer.
every integer that is not odd is divisible by 2.
the square of a number is nonnegative.

2,3,and 5 are the wrong ones

Step-by-step explanation:

A number squared is produced when you take the number ... If -a is in the set of positive numbers, then, by property P12

I think is

POSITIVE

In mathematics, a square root of a number x is a number y such that y2 = x; in other words, a number y whose square (the result of multiplying the number by itself, or y ⋅ y) is x. For example, 4 and −4 are square roots of 16, because 42 = (−4)2 = 16. Every nonnegative real number x has a unique nonnegative square root, called the principal square root, which is denoted by √x, where the symbol √ is called the radical sign or radix. For example, the principal square root of 9 is 3, which is denoted by √9 = 3, because 32 = 3 ⋅ 3 = 9 and 3 is nonnegative. The term (or number) whose square root is being considered is known as the radicand. The radicand is the number or expression underneath the radical sign, in this case 9.Every positive number x has two square roots: √x, which is positive, and −√x, which is negative. Together, these two roots are denoted as ±√x (see ± shorthand). Although the principal square root of a positive number is only one of its two square roots, the designation "the square root" is often used to refer to the principal square root. For positive x, the principal square root can also be written in exponent notation, as x1/2.

Square roots of negative numbers can be discussed within the framework of complex numbers. More generally, square roots can be considered in any context in which a notion of "squaring" of some mathematical objects is defined. These include algebras of matrices, endomorphism rings, among other mathematical structures

square root

Step-by-step explanation:

Note that any positive real number has two square roots, one positive and one negative. For example, the square roots of 9 are and , since . Any nonnegative real number has a unique nonnegative square root ; this is called the principal square root

yes because if you square a negative number the answer will be positive

Step-by-step explanation:

example.

3^2=9

(-3)^2=9

Step-by-step explanation:

The square of the number is non-negative.

Any signed number squared yields a positive result.

The produce of like sign

Example:

The number is -2.

Square -2  ⇒   (-2)(-2) = +4  ⇒ a non-negative number

The number is +5.

Square +5  ⇒  (+5)(+5) = +25  ⇒ a non-negative number
