## What is the value of i?

If you are familiar with complex numbers, the “imaginary” number i has the property that the square of i is -1. It is a rather curious fact that i raised to the i-th power is actually a real number! In fact, its value is approximately 0.20788.

## What is 2i equal to?

The absolute value of the complex number, 2i, is 2.

What is value of imaginary number?

Essentially, an imaginary number is the square root of a negative number and does not have a tangible value. While it is not a real number — that is, it cannot be quantified on the number line — imaginary numbers are “real” in the sense that they exist and are used in math.

What is the i thing in math?

The symbol i in mathematical equations may refer to; Imaginary unit (i), for which i2 = -1. Imaginary number. Complex number.

### What is the value of negative I?

The imaginary number, when multiplied by itself, gives a negative value. For example, consider an imaginary number 3i, if multiplied by itself or if we take the square of 3i, gives 9i2 or we can write it as -9.

### What is the value of 10 power?

Thus, shown in long form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000. When n is less than 0, the power of 10 is the number 1 n places after the decimal point; for example, 10−2 is written 0.01.

What is 5i equal to?

If x = 0, the z is called a purely imaginary number and when y = 0, z is called the purely real number. In the same way can write 5i and is equal to 0 + 5i….Thank you.

What is 8i?

+8. I believe it means the imaginary number. Imaginary number is what you get when you take the square root of negative numbers since no actual number when squared gives a negative result, people made up a number and the name imaginary numbers sticked to it. …

## Is 0 real or imaginary?

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 is I equal to in math?

[math] i / i [/math] equals 1, just like anything else would if it were divided by itself. After all, division is just a fancy way of saying how many groups of a certain number you can make out of multiple objects.

### What does the approximate value mean in math?

### How to find the average in math?

Part 2 of 2: Finding the Weighted Average Write down the average of each category. Use the method of finding the average — adding up all of the numbers in the set and dividing the result by Write down the weight category of each average. Remember that the weight categories should add up to 100%. Multiply each average by its weight category. Add the results.

What is the imaginary number i equal to?

Students learn that the imaginary number “i” is equal to the square root of –1, which means that i^2 is equal to (the square root of –1) squared, which equals –1. Students also learn to simplify imaginary numbers.
