The simplified form of complex expression is -14+4i

A is correct.

Step-by-step explanation:

Given: 8i^6+6i^5-5i^3-3i^2-7i-9

As we know, i^2=-1

i^6=-1

i^5=i

Put the value and simplify i

$\Rightarrow 8(-1)+6(i)-5(-i)-3(-1)-7i-9$

$\Rightarrow -8+6i+5i+3-7i-9$ 3

Combine the like term and simplify it

$\Rightarrow (-8+3-9)+(6i+5i-7i)$

$\Rightarrow -14+4i$

Hence, The simplified form of complex expression is -14+4i
