Simplify (-x^3)(x)(x^5)

$(- x^{3}) (x) (x^{5})$

Step 1

Multiply $x^{3}$ by $x$ by adding the exponents.

Move $x$ .

$- (x \cdot x^{3}) x^{5}$

Multiply $x$ by $x^{3}$ .

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

$- (x^{1} x^{3}) x^{5}$

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

$- x^{1 + 3} x^{5}$

Add $1$ and $3$ .

$- x^{4} x^{5}$

Step 2

Multiply $x^{4}$ by $x^{5}$ by adding the exponents.

Move $x^{5}$ .

$- (x^{5} x^{4})$

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

$- x^{5 + 4}$

Add $5$ and $4$ .

$- x^{9}$
