Answer 2

Answer:

Step-by-step explanation:

Concept:

A number that may be expressed without a fractional component is referred to as an integer (from the Latin integer, meaning "whole"). For instance, the numbers$21, 4, 0,$ and $2048$ are all integers, although $9.75$, $5+1/2$, and $\sqrt2$ are not.

The positive natural numbers (1, 2, 3,...), often known as whole numbers or counting numbers, and their additive inverses (the negative integers, i.e., 1, 2, 3,...) make up the set of integers. The blackboard bold (mathbb Z) or boldface (Z) letter, which originally stood for the German word Zahlen, is frequently used to represent the set of integers ("numbers").

The set of all rational numbers, displayed as mathbb Q mathbb Q, is a subset of the real numbers, displayed as mathbb R mathbb R, which is a subset of  Z is countably infinite, just like the natural numbers.

The lowest group and ring of the natural numbers are formed by the integers. To distinguish them from the more generic algebraic integers, the integers in algebraic number theory are occasionally designated as rational integers. In actuality, (rational) integers are rational numbers that are also algebraic integers.

Given:

all possible pairs of integers that give a product of -40.​

Find:

all possible pairs of integers that give a product of -40.​

Solution:

given that find all possible pairs of integers that give a product of -40.​

$1*(-40)$

$2*(-20)$

$4*(-10)$

$5*(-8)$

$8*(-5)$

$10*(-4)$

$20*(-2)$

$40*(-1)$
