An imaginary number is the square root of -1.
It is written in algebra in the form a + ib. The a is the real part and the b is the imaginary part.
An example of an imaginary number in real life is the distance in a mirror. Let's say you are standing three feet in front of the mirror. Then you are 3 + 3i feet in front of your mirror image. You are three real feet in front of the mirror and three imaginary feet back in the mirror's reflection.
What else can I help you with?
In algebra what is the square root of -36?
6i which also means 6 as an imaginary number.
What does i mean in algebra?
i means imaginary number or what you would find the square root of to make -1
What does i mean in mathematics?
The symbol "i" is an imaginary number used in algebra, equal to the square root of negative one.
Can a number be imaginary but not pure imaginary?
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
Can a no real number be a pure imaginary number?
If a number is pure imaginary then it has no real component. If it is a real number, then there is no imaginary component. If it has both real and imaginary components, then it is a complex number.
Can you divide an imaginary number by a real number?
an imaginary number is imaginary so no (i guess) this answer kind of sucks
How do you simplify the imaginary number -125?
-125 is NOT an imaginary number.
What does 7 divided by imaginary number equal?
That quotient would be an imaginary number. The actual number depends on exactly what imaginary number you divide the 7 by.
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).
Is -23 an imaginary number?
No, but √-23 is. An imaginary number is the square root of a negative number.
Is Algebra II similar to Algebra I?
Math is taught like this: Pre-Algebra, Algebra I, Geometry, Algebra 2, Pre-Calculus, Calculus, Trigonometry. Algebra I is similar to Algebra 2, but Algebra 2 has more difficult concepts, such as imaginary numbers. Added: I would have put statistics and trig in between Algebra 2 and Pre-calculus. You review trig in precalculus and statistics is the first transferable math course in college.
Whats an imaginary number?
