Answer:

Step-by-step explanation:

Use KCF method for fraction division.

Keep the first fraction

Change the operation to multiplication

Flip the second fraction.

1) 3÷ (1/4) = 3*\frac{4}{1}= 12

2) 7 ÷ (1/2) = 7 * \frac{2}{1}=14

3) (1/5) ÷ (1/20) = \frac{1}{5}*\frac{20}{1}=4

4) (1/2) ÷ (1/10) = \frac{1}{2}*\frac{10}{1}=5

5) (1/7) ÷ 3 = \frac{1}{7}*\frac{1}{3}=\frac{1}{21}

Okay so here are the steps....

(5 + 2i) + (8 - 3i)       <---- when we have exponents we should worry about the                                            "i" because it is equal to √-1 but here it isn't the case.
<u>

(13 - i)</u>
