Step 2

Simplify.

Multiply $x^{2}$ by $x$ by adding the exponents.

Move $x$ .

$3 (x \cdot x^{2}) (2 y) + 3 x^{2} (- 3 x y^{2}) + 3 x^{2} (4 x^{2} y^{3})$

Multiply $x$ by $x^{2}$ .

Raise $x$ to the power of $1$ .

$3 (x^{1} x^{2}) (2 y) + 3 x^{2} (- 3 x y^{2}) + 3 x^{2} (4 x^{2} y^{3})$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$3 x^{1 + 2} (2 y) + 3 x^{2} (- 3 x y^{2}) + 3 x^{2} (4 x^{2} y^{3})$

Add $1$ and $2$ .

$3 x^{3} (2 y) + 3 x^{2} (- 3 x y^{2}) + 3 x^{2} (4 x^{2} y^{3})$

Multiply $x^{2}$ by $x$ by adding the exponents.

Move $x$ .

$3 x^{3} (2 y) + 3 (x \cdot x^{2}) (- 3 y^{2}) + 3 x^{2} (4 x^{2} y^{3})$

Multiply $x$ by $x^{2}$ .

Raise $x$ to the power of $1$ .

$3 x^{3} (2 y) + 3 (x^{1} x^{2}) (- 3 y^{2}) + 3 x^{2} (4 x^{2} y^{3})$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$3 x^{3} (2 y) + 3 x^{1 + 2} (- 3 y^{2}) + 3 x^{2} (4 x^{2} y^{3})$

Add $1$ and $2$ .

$3 x^{3} (2 y) + 3 x^{3} (- 3 y^{2}) + 3 x^{2} (4 x^{2} y^{3})$

Multiply $x^{2}$ by $x^{2}$ by adding the exponents.

Move $x^{2}$ .

$3 x^{3} (2 y) + 3 x^{3} (- 3 y^{2}) + 3 (x^{2} x^{2}) (4 y^{3})$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$3 x^{3} (2 y) + 3 x^{3} (- 3 y^{2}) + 3 x^{2 + 2} (4 y^{3})$

Add $2$ and $2$ .

$3 x^{3} (2 y) + 3 x^{3} (- 3 y^{2}) + 3 x^{4} (4 y^{3})$

Step 3

Simplify each term.
