Answer 3

Simplifying
20x(8xy20)(-10x10y10)

Remove parenthesis around (8xy20)
20x * 8xy20(-10x10y10)

Remove parenthesis around (-10x10y10)
20x * 8xy20 * -10x10y10

Reorder the terms for easier multiplication:
20 * 8 * -10x * xy20 * x10y10

Multiply 20 * 8
160 * -10x * xy20 * x10y10

Multiply 160 * -10
-1600x * xy20 * x10y10

Multiply x * xy20
-1600x2y20 * x10y10

Multiply x2y20 * x10y10
-1600x12y30
