\frac{10}{1 + 3i} =  \frac{10}{1 + 3i} * \frac{1-3i}{1-3i} =  \frac{10-30i}{1^{2} -(3i)^{2}} = \frac{10-30i}{1 -9 i^{2} } = \frac{10-30i}{1 -9*(-1)} = \frac{10(1-3i)}{1+9}= \frac{10(1-3i)}{10} = 1 -3i

sdas [7]

Step-by-step explanation:

first, add 3 and 5 together to get the sandwiches robert already made. so you should get 8.

Now, subtract 12 and 8 to get the ham sandwiches (the rest). you should get 4.

So, 4 ( the ham ) should be fractured by 12 ( all kinds of sandwiches robert already made. now your final answer should be :

4/12

How do you write it:

3 + 5

= 8

= 12 - 8

= 4

= 4/12 #

now, 4/12 is already correct. however, you may have to simplify the equation. so now, your final answer should be:

1/3

(my english is not so good so i hope you can understand my explanation well enough.)
