simplify (3y)(-2y^8)

Solution

simplify

(3 y) (- 2 y^{8})

Solution

- 6 y^{9}

Solution steps

(3 y) (- 2 y^{8})

Apply rule:

a (- b) = - ab

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

= - 3 y \cdot 2 y^{8}

Multiply the numbers:

- 3 \cdot 2 = - 6

= - 6 y y^{8}

Apply exponent rule:

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

y y^{8} = y^{1 + 8}

= - 6 y^{1 + 8}

Add the numbers:

1 + 8 = 9

= - 6 y^{9}
