What type of number is pi?

Pi is an irrational number

Step-by-step explanation:

Pi is an irrational number because it cannot be written down as a simple fraction.

We know that pi is a number that never ends. Its decimals can be written out forever endlessly. Therefore, it must be an irrational number.

Step-by-step explanation:

First, let us go over the different types of numbers:

Natural Numbers - 1, 2, 3, ...

Whole Numbers - All natural numbers including 0

Integers - All whole numbers, both positive and negative

Rational Numbers - All numbers, both positive and negative that can be represented as a fraction. In other words, they have a terminating decimal point

Irrational Numbers - Numbers that cannot be written as a fraction. Numbers who have an infinite number of decimal points

Real Numbers - Includes everything else listed.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
