### How can you tell which part of a complex number is the real part and which is the imaginary part?

The imaginary part is expressed as a product of i(square root of negative one), typically following a plus sign, so that the complex number has the form a + bi, with "a" the real part and "bi" the imaginary part.

### How do you write complex numbers in the form a plus bi?

A complex number comes in two parts: a real part and an imaginary part. If the value of the real part is a and the value of the imaginary part is b, the number is written as a + bi.

### What is a number added to 9 in math?

Any number, real or imaginary, can be the sum of another number plus 9.

### The set of complex numbers contains only numbers of the form a plus bi where a and b are positive numbers and you is the imaginary unit?

Not exactly. The numbers (a & b) can be any real number (positive or negative). It is the letter i, which represents the imaginary unit sqrt(-1).False

### What is the square root of the imaginary number i?

It is plus or minus ( 1 + i) / sqrt(2) multiply together and you get i

### Whats real numbers?
