Solution

simplify

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

Solution

- 32 x^{5}

Solution steps

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

Apply rule:

a (- b) = - ab

(8 x^{2}) (- 4 x^{3}) = - 8 x^{2} \cdot 4 x^{3}

= - 8 x^{2} \cdot 4 x^{3}

Multiply the numbers:

- 8 \cdot 4 = - 32

= - 32 x^{2} x^{3}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

x^{2} x^{3} = x^{2 + 3}

= - 32 x^{2 + 3}

Add the numbers:

2 + 3 = 5

= - 32 x^{5}
