simplify (-4i)^3*2i

Solution

simplify

(- 4 i)^{3} \cdot 2 i

Solution

- 128

Solution steps

(- 4 i)^{3} \cdot 2 i

Simplify

(- 4 i)^{3} : 64 i

= 64 i 2 i

Multiply the numbers:

64 \cdot 2 = 128

= 128 ii

Apply exponent rule:

aa = a^{2}

ii = i^{2}

= 128 i^{2}

Apply imaginary number rule:

i^{2} = - 1

= 128 (- 1)

Multiply the numbers:

128 (- 1) = - 128

= - 128
