expand-2x(-2x^3)

Solution

expand

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

Solution

4 x^{4}

Solution steps

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

Apply rule

- (- a) = a

= 2 x \cdot 2 x^{3}

Multiply the numbers:

2 \cdot 2 = 4

= 4 x^{3} x

Apply exponent rule:

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

x x^{3} = x^{1 + 3}

= 4 x^{1 + 3}

Add the numbers:

1 + 3 = 4

= 4 x^{4}
