Solution

simplify

- 8 i^{20}

Solution

- 8

Solution steps

- 8 i^{20}

Apply exponent rule:

a^{b c} = (a^{b})^{c}

i^{20} = (i^{2})^{10}

= - 8 (i^{2})^{10}

Apply imaginary number rule:

i^{2} = - 1

= - 8 (- 1)^{10}

(- 1)^{10} = 1

= - 8 \cdot 1

Multiply the numbers:

- 8 \cdot 1 = - 8

= - 8
