7 - 24i

Step-by-step explanation:

(4−3i)(4−3i)(4-3i)(4-3i).

(4−3i)(4−3i)(4-3i)(4-3i)

Expand (4−3i)(4−3i)(4-3i)(4-3i) using the FOIL Method.

Apply the distributive property.

4(4−3i)−3i(4−3i)4(4-3i)-3i(4-3i)

Apply the distributive property.

4⋅4+4(−3i)−3i(4−3i)4⋅4+4(-3i)-3i(4-3i)

Apply the distributive property.

4⋅4+4(−3i)−3i⋅4−3i(−3i)4⋅4+4(-3i)-3i⋅4-3i(-3i)

Blababa [14]

8 goes with 3/5: 10 goes with n (n being the number of cups)

$\frac{8}{3/5} = \frac{10}{n}$

Use cross products and we get 8n = 6
Now divide by 8
8n = 6
8 8

n= 6/8 or 3/4 of a cup of flour.
