simplify (5n)(-4n^2)

Solution

simplify

(5 n) (- 4 n^{2})

Solution

- 20 n^{3}

Solution steps

(5 n) (- 4 n^{2})

Apply rule:

a (- b) = - ab

(5 n) (- 4 n^{2}) = - 5 n \cdot 4 n^{2}

= - 5 n \cdot 4 n^{2}

Multiply the numbers:

- 5 \cdot 4 = - 20

= - 20 n n^{2}

Apply exponent rule:

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

n n^{2} = n^{1 + 2}

= - 20 n^{1 + 2}

Add the numbers:

1 + 2 = 3

= - 20 n^{3}
