## Which of the following is a conjugated acid-base pair?

Hence H3PO4 and H2PO4− is a conjugate acid-base pair.

## What is the conjugate?

Conjugate is what you do to a word to make it agree with other words in a sentence. To conjugate the verb to be, you’d say “I am,” “you are,” “she is,” and so on. You’re changing the form of the verb to make it agree with the subject. You might conjugate other words to make them agree in number, gender, or tense.

## How do you use conjugate?

The conjugate of a two-term expression is just the same expression with subtraction switched to addition or vice versa. The product of conjugates is always the square of the first thing minus the square of the second thing. Cancel the (x – 4) from the numerator and denominator. Now substitution works.

## What is multiply by conjugate?

Multiply it by the conjugate! Or, more accurately, multiply both the numerator and the denominator by the conjugate. This will essentially move the radical to the numerator, leaving you with a radical-free denominator. This fraction is relatively simple, but there’s a radical in the denominator.

## What is the conjugate of 0?

If we are given an imaginary zero, we can sometimes use the conjugate zeros theorem to factor the polynomial and find other zeros. The conjugate zeros theorem says that if a polynomial has one complex zero, then the conjugate of that zero is a zero itself.

## How do you find the conjugate of a product?

For a complex number a + bi, the conjugate is a – bi.

1. For 2 – 3i, the conjugate is 2 – (-3i) = 2 + 3i. (2-3i)(2+3i) = 4 + 6i – 6i – 9i2 = 4 + 9 = 13 [Use the FOIL method] Note that the product is always a real number.
2. For -3 + 4i, the conjugate is -3 – 4i. (-3+4i)(-3-4i) = __________
3. Can you do #3 on your own?

## What is the product of 3 I and its conjugate?

We can conclude that the product of the multiplication of the complex number 3+3i and its conjugate, 3-3i, is 18.

## How do you plot a complex conjugate?

How To: Given a complex number, represent its components on the complex plane.

1. Determine the real part and the imaginary part of the complex number.
2. Move along the horizontal axis to show the real part of the number.
3. Move parallel to the vertical axis to show the imaginary part of the number.
4. Plot the point.

## What does complex conjugate mean?

In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign.

## 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 simplify imaginary numbers?

A simple shortcut to simplify an imaginary unit raised to a power is to divide the power by 4 and then raise the imaginary unit to the power of the reminder. For example: to simplify j23, first divide 23 by 4. 23/4 = 5 remainder 3. So j23 = j3 = -j …… as already shown above.

## Is 0 an imaginary number?

An imaginary number is the square root of a nonpositive real number. Since zero is nonpositive, and is its own square root, zero can be considered imaginary.
