Imaginary Solution v2

Algebra Level 3

log 2 ( ( x i + 1 ) ( x i 5 ) arcsin ( 0.6 ) ) = 8 \log_2\left(\left(xi+1\right)\left(xi-5\right)\cdot\arcsin\left(0.6\right)\right)=8

Solve for the greatest value possible of Im(x). then round it to a whole number.

(Im(value) is a function to determine the imaginary part e.g: Im(3+5i) = 5)


The answer is 18.
