Can a complex number be imaginary?
Yes, imaginary numbers are a subset of complex numbers.
What are the characteristics of a complex number?
A complex number must have a real and imaginary part. It can be in the form: a + bi i is an imaginary number and a and b are real numbers
What is subset of imaginary numbers?
A subset of imaginary numbers consists of numbers that can be expressed in the form (bi), where (b) is a real number and (i) is the imaginary unit, defined as (i = \sqrt{-1}). This subset includes numbers like (2i), (-3.5i), and (0.1i). Imaginary numbers can be thought of as a special case of complex numbers, which have both a real part and an imaginary part.
How do you write complex numbers in the form a plus bi?
A complex number comes in two parts: a real part and an imaginary part. If the value of the real part is a and the value of the imaginary part is b, the number is written as a + bi.
What is the standard form of complex numbers?
a + bi. a & b are both real numbers. the number i is the imaginary unit equal to the positive square root of -1.

Fomular for complex numbers?
A complex number is a number with a real part and an imaginary part. It is written in the form a+bi. a is the real part & bi is the imaginary part. Recall that i = square root of -1. An example would be 2+3i.
Is Every complex number is a pure imaginary number?
No. All Complex Numbers are of the form a + bi where a and b are Real Numbers and i is the square root of -1. So only ones where a = 0 are pure Imaginary Numbers.
The set of complex numbers contains only numbers of the form a plus bi where a and b are positive numbers and you is the imaginary unit?
Not exactly. The numbers (a & b) can be any real number (positive or negative). It is the letter i, which represents the imaginary unit sqrt(-1).False
What are considered complex numbers?
A complex number is any number that can be represented in the form of a+bi, the real numbers are a and b, the imaginary number is i. Complex numbers are used in scientific and engineering fields.
What are imaginary numbe?
Imaginary numbers are a class of numbers that extend the real number system, defined as multiples of the imaginary unit (i), where (i) is the square root of (-1). They allow for the solution of equations that do not have real solutions, such as (x^2 + 1 = 0). Imaginary numbers are often used in complex numbers, which combine real and imaginary parts in the form (a + bi), where (a) and (b) are real numbers. They have important applications in fields such as engineering, physics, and mathematics.
How do you tell a real number?
It has no imaginary part. A complex number is of the form a + bi where a and b are real numbers, and i = √-1. A real number has b = 0.
How do you multiply imaginary numbers?
First, let's make sure we are not confusing imaginary numbers with complex numbers. Imaginary (sometimes called "pure imaginary" for clarity) numbers are numbers of the form ai, where a is a real number and i is the principal square root of -1. To multiply two imaginary numbers ai and bi, start by pretending that i is a variable (like x). So ai x bi = abi2. But since i is the square root of -1, i2=-1. So abi2=-ab. For example, 6i x 7i =-42. 5i x 2i =-10. (-5i) x 2i =-(-10)= 10. Complex numbers are numbers of the form a+bi, where a and b are real numbers. a is the real part, bi is the imaginary part. To multiply two complex numbers, again, just treat i as if it were a variable and then in the final answer, substitute -1 wherever you see i2. Hence (a+bi)(c+di) = ac + adi + bci + dbi2 which simplifies to ac-db + (ad+bc)i. For example: (2+3i)(4+5i) = 8 + 10i +12i + 15i2= 8 + 10i + 12i - 15 = -7 + 22i
