Answer 2

To simplify the expression, let's expand and combine like terms:

Expression: -7t(2t(8) - 3k) + 5(4t(10) - 2k)

Step 1: Distribute the constants -7t and 5 to the terms inside the parentheses:

-7t * 2t * 8 + 7t * 3k + 5 * 4t * 10 - 5 * 2k

Step 2: Simplify each term:

-14t^2 * 8 + 21tk + 20t * 10 - 10k

Step 3: Combine like terms:

-112t^2 + 21tk + 200t - 10k

The simplified expression is: -112t^2 + 21tk + 200t - 10k
