Expand Using the Binomial Theorem (8p+3q)^4

${(8 p + 3 q)}^{4}$

Step 1

Use the binomial expansion theorem to find each term. The binomial theorem states ${(a + b)}^{n} = \sum_{k = 0}^{n} n C k \cdot (a^{n - k} b^{k})$ .

$\sum_{k = 0}^{4} \frac{4!}{(4 - k)! k!} \cdot {(8 p)}^{4 - k} \cdot {(3 q)}^{k}$

Step 2

Expand the summation.

$\frac{4!}{(4 - 0)! 0!} \cdot {(8 p)}^{4 - 0} \cdot {(3 q)}^{0} + \frac{4!}{(4 - 1)! 1!} \cdot {(8 p)}^{4 - 1} \cdot {(3 q)}^{1} + \frac{4!}{(4 - 2)! 2!} \cdot {(8 p)}^{4 - 2} \cdot {(3 q)}^{2} + \frac{4!}{(4 - 3)! 3!} \cdot {(8 p)}^{4 - 3} \cdot {(3 q)}^{3} + \frac{4!}{(4 - 4)! 4!} \cdot {(8 p)}^{4 - 4} \cdot {(3 q)}^{4}$
