8x4=32
32+40=72
72/2=36
36+6=42
The number is 42
Step 1. Use Multiplication Distributive Property
4*3^3(x^2)^3(y^4)^3
Step 2. Simplify 3^3 to 27
4*27(x^2)^3(y^4)^3
Step 3. Use the Power Rule
4*27x^6(y^4)^3
Step 4. Use the Power Rule
4*27x^6y^12
Step 5. Simplify.
The answer is 108x^6y^12
Answer:
Remember, the expansion of
is
, where
.
Then,

Then, the coefficient of the term
is 
a) since 6-k=2, then k=4. So the coefficient of
is

b) since 6-k=5, then k=1. So, the coefficient of
is

c) since 6-k=3, then k=3. So, the coefficient of
is
