What is the magnitude and phase of x.

Step-by-step explanation:

First you assume some complex number of the form

Then you assume the real part of the left is equal to 3 and the complex part

Then you simplify the 2nd equation to

You multiply the whole equation by

We let

We then go back to the definition of

But since a is a real number we only use the first result:

We then solve for

We then write the newly achieved complex number:

.

Use which equation you please to find the magnitude of:

- the magnitude.

And to find the phase/angle.

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
