expand-3j(3j^2)

Solution

expand

- 3 j (3 j^{2})

Solution

- 9 j^{3}

Solution steps

- 3 j (3 j^{2})

Remove parentheses:

(a) = a

= - 3 j \cdot 3 j^{2}

Multiply the numbers:

3 \cdot 3 = 9

= - 9 j^{2} j

Apply exponent rule:

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

j j^{2} = j^{1 + 2}

= - 9 j^{1 + 2}

Add the numbers:

1 + 2 = 3

= - 9 j^{3}
