When solving (-2)5(-2)-8, you would first, following PEMDAS ofcourse, multiply -2 and 5, getting -10. Then you would multiply -2 and -10, which would be positive 20. Lastly, you would subtract 8 from 20, which equals 12.
I cannot find an answer within the options you gave me, but I am 100% sure that (-2)5(-2)-8 equals 12.
Hope this helped in some way! Please mark brainliest! Thank you v much! :)
