simplify (3y)(-5y^2)

Solution

simplify

(3 y) (- 5 y^{2})

Solution

- 15 y^{3}

Solution steps

(3 y) (- 5 y^{2})

Apply rule:

a (- b) = - ab

(3 y) (- 5 y^{2}) = - 3 y \cdot 5 y^{2}

= - 3 y \cdot 5 y^{2}

Multiply the numbers:

- 3 \cdot 5 = - 15

= - 15 y y^{2}

Apply exponent rule:

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

y y^{2} = y^{1 + 2}

= - 15 y^{1 + 2}

Add the numbers:

1 + 2 = 3

= - 15 y^{3}
