The answer depends on the context, but bi is a variable, not a number. It could be the ith of a set of variables b1, b2, ... .
Or it could be the square root of -b2.
Or it could be a vector of magnitude b in the idirection.

What is a number that can be written in the form a plus bi where a and b are real numbers?
A number of the form (a + bi) is a complex number.
A number written in the form a bi is called a number?
Complex
A number written in the form a plus bi is called a number?

What complex number is a number of the form a plus bi where?
"a + bi" is a common way to write a complex number. Here, "a" and "b" are real numbers.Another common way to write a complex number is in polar coordinates - basically specifying the distance from zero, and an angle.
What is the Multiplicative inverse formula of complex numbers?
So if you have a number z = a + bi. Then how to find 1 divided by z. The way to figure this is to get the denominator as a pure real number. Multiplying the numerator and the denominator by the complex conjugate {a - bi} will result in a pure real denominator.(a - bi)(a + bi) = a² + abi - abi - (bi)² = a² + b². So the multiplicative inverse is(a - bi)/(a² + b²)
What number indicates the prefix bi?
The prefix Bi- represents the number 2.
Is the difference of a complex number and it's conjugate an imaginary number?
Yes. By definition, the complex conjugate of a+bi is a-bi and a+bi - (a - bi)= 2bi which is imaginary (or 0)
Which element is bi?
Bi shows the element bismuth. Atomic number if Bi is 83.
How do conjugate arrive at complex number?
Complex numbers form: a + bi where a and b are real numbers. The conjugate of a + bi is a - bi If you multiply a complex number by its conjugate, the product will be a real number, such as (a + bi)(a - bi) = a2 - (bi)2 = a2 - b2i2 = a2 - b2(-1) = a2 + b2
What is a number that can be written in the form a plus bi where a and b are real numbers?
A number of the form (a + bi) is a complex number.
What number does bi mean?
2
The sum of a complex number and its conjugate?
Given a complex number z = a + bi, the conjugate z* = a - bi, so z + z*= a + bi + a - bi = 2*a. Note that a and b are both real numbers, and i is the imaginary unit: +sqrt(-1).
A number written in the form a bi is called a number?
Complex
Is the difference of a complex number and its conjugate a real imaginary or pure imaginary number?
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
What is the phone number of the Bloomer Bi-Centennial House in Bloomer Wisconsin?
The phone number of the Bloomer Bi-Centennial House is: 715-568-1776.
A number written in the form a plus bi is called a number?
complex
Why do you multiply by the complex conjugate?
Whenever a complex number (a + bi) is multiplied by it's conjugate (a - bi), the result is a real number: (a + bi)* (a - bi) = a2 - abi + abi - (bi)2 = a2 - b2i2 = a2 - b2(-1) = a2 + b2 This is useful when dividing complex numbers, because the numerator and denominator can both be multiplied by the denominator's conjugate, to give an equivalent fraction with a real-number denominator.
