Simplify x^4(-3x^2)

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

Step 1

Rewrite using the commutative property of multiplication.

$- 3 x^{4} x^{2}$

Step 2

Multiply $x^{4}$ by $x^{2}$ by adding the exponents.

Move $x^{2}$ .

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

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

$- 3 x^{2 + 4}$

Add $2$ and $4$ .

$- 3 x^{6}$
