The first step we have to do is: 2/3 × 2. If it is multiplying a whole number to a fraction, multiply the whole number by the numerator. In this case, the numerator is 2, so we can do: 2 × 2 to get 4.

From multiplying, our new fraction would look like: 4/3. You can keep it as an improper fraction or you can turn it into a mixed fraction. To do so, divide the numerator by the denominator (4 ÷ 3) to get the answer of 1.3333, Keep the original denominator, write the remainder as the numerator, and whatever whole number you get, goes in front of the fraction. Since 4 ÷ 3 = 1 with a remainder of 1, we can keep the denominator, and switch out the numerator with 1, and also the whole number.

The answer as an improper fraction: 4/3
The answer as a mixed fraction: 1 1/3
The answer as a decimal: 1.3333

Simplified form of (3-5i)^2

Answers

Answer:

-16 - 30i

Step-by-step explanation:

(3-5i)^2 = (3-5i) * (3-5i)

Applying the "FOIL" method of expanding this expression through multiplication, we get:

9 - 15i - 15i - 25 (since i^2 = -1)

Simplifying this result, we get -16 - 30i
