{(2 x^{3} + 1)}^{5}

${(2 x^{3} + 1)}^{5}$

Step 1

Pascal's Triangle can be displayed as such:

1

$1$

1 - 1

$1 - 1$

1 - 2 - 1

$1 - 2 - 1$

1 - 3 - 3 - 1

$1 - 3 - 3 - 1$

1 - 4 - 6 - 4 - 1

$1 - 4 - 6 - 4 - 1$

1 - 5 - 10 - 10 - 5 - 1

$1 - 5 - 10 - 10 - 5 - 1$

The triangle can be used to calculate the coefficients of the expansion of

{(a + b)}^{n}

${(a + b)}^{n}$ by taking the exponent

n

$n$ and adding

1

$1$ . The coefficients will correspond with line

n + 1

$n + 1$ of the triangle. For

{(2 x^{3} + 1)}^{5}

${(2 x^{3} + 1)}^{5}$ ,

n = 5

$n = 5$ so the coefficients of the expansion will correspond with line

6

$6$ .

Step 2

The expansion follows the rule

{(a + b)}^{n} = c_{0} a^{n} b^{0} + c_{1} a^{n - 1} b^{1} + c_{n - 1} a^{1} b^{n - 1} + c_{n} a^{0} b^{n}

${(a + b)}^{n} = c_{0} a^{n} b^{0} + c_{1} a^{n - 1} b^{1} + c_{n - 1} a^{1} b^{n - 1} + c_{n} a^{0} b^{n}$ . The values of the coefficients, from the triangle, are

1 - 5 - 10 - 10 - 5 - 1

$1 - 5 - 10 - 10 - 5 - 1$ .

1 a^{5} b^{0} + 5 a^{4} b + 10 a^{3} b^{2} + 10 a^{2} b^{3} + 5 a b^{4} + 1 a^{0} b^{5}

$1 a^{5} b^{0} + 5 a^{4} b + 10 a^{3} b^{2} + 10 a^{2} b^{3} + 5 a b^{4} + 1 a^{0} b^{5}$

Step 3
