Answer:

Multiplying a complex number by a real number

Explanation:

For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0. Similarly, when you multiply a complex number z by 1/2, the result will be half way between 0 and z.

Answer:

4^(-2)

Step-by-step explanation:

4^6 * 4^-8

Since the bases are the same, and we are multiplying, we can add the exponents

4^(6-8)

How would u do 1 over 3 y + 1 over 4 = 5 over 12? I forgot my notes:(

malfutka [58]

Is it
$\frac{1}{3y} + \frac{1}{4} = 5$
or
$\frac{1}{3} y + \frac{1}{4} = 5$
?

both start out the same, just remember what you do to one side you have to do to the other, so subtract both sides by 1/4, then you want to get y alone, so either divide or multiply the 3 on both sides! let me know which it is and I can help you out more

[edit] it's the second, and not going to use cross multiplication.
added a picture that walks you through it :)
