i is equalled to the square root of -1.
The square root is a number which, multiplied by itself, will give a number (eg: 2 is the square root of 4 because 2x2=4)
But negative numbers can't have square roots because any number multiplied by itself will be positive.
So 'i' is imaginary.
You use 'i' in calculus to figure out complex problems.
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
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.
an imaginary number is imaginary so no (i guess) this answer kind of sucks
-125 is NOT an imaginary number.
That quotient would be an imaginary number. The actual number depends on exactly what imaginary number you divide the 7 by.
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
No, but √-23 is. An imaginary number is the square root of a negative number.
An imaginary number is a number that has the square root of -1 as one of its factors.
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
No. It is an imaginary (or complex) number.
No, it is an imaginary number which is a complex number.
The imaginary unit number is the square root of -1 and is denoted by i
