## What is the number I?

The imaginary unit or unit imaginary number (i) is a solution to the quadratic equation x2 + 1 = 0. Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication.

## What is i equal to in math?

The unit imaginary number, i, equals the square root of minus 1.

## How do you simplify complex numbers?

To find the final simplified version of the sum, put the real part and the imaginary part back together. The result is the simplified sum of the complex numbers. The sum of (a+bi) and (c+di) is written as (a+c) + (b+d)i. Applying the numerical example, the sum of (3+3i) + (5-2i) is 8+i.

## How do you divide complex numbers?

To divide complex numbers, you must multiply by the conjugate. To find the conjugate of a complex number all you have to do is change the sign between the two terms in the denominator. Step 2: Distribute (or FOIL) in both the numerator and denominator to remove the parenthesis.

## What is 4 3i divided by its conjugate?

Dividing Complex Numbers The conjugate of 4 + 3i is found by retaining the real part (4) and reversing only the sign of the imaginary part (that is, 3i becomes -3i) (4 + 3i)(4 – 3i) = 16 – 12i + 12i – 9i2 Notice that -12i and 12i cancel.

## What is the conjugate of 7 5i?

Let’s start with your school’s answer. If you do (7-5i)*(-7+5i), you get 49 +70i-25i^2. This, in simplified form, is equal to 74+70i, which is a complex number, not a real number. Therefore, 7+5i has to be the conjugate of 7-5i.

## How do you know if a number is imaginary?

An imaginary number is a number that, when squared, has a negative result. Essentially, an imaginary number is the square root of a negative number and does not have a tangible value.

## What is imaginary number equal to?

The imaginary part of a complex number contains the imaginary unit, ı. This number is called imaginary because it is equal to the square root of negative one.

## Is 0 an imaginary number?

Is 0 an imaginary number? Since an imaginary number is the square root of a nonpositive real number. And zero is nonpositive and is its own square root, so zero can be considered as an imaginary number.

## What kind of number is 100?
