Final answer:
To evaluate the expression (a³b-2 + c)² when a = -2, b = 3, and c = -5, substitute the given values into the expression and simplify. The result is 961.
Step-by-step explanation:
To evaluate the expression (a³b-2 + c)², we substitute the given values a = -2, b = 3, and c = -5 into the expression.
Plugging in these values, we get (-2³(3)-2 + (-5))². Simplifying, we have (-8(3)-2 + (-5))² which becomes (-24-2-5)² and further simplifies to (-31)².
Finally, evaluating (-31)², we have (-31)(-31) = 961. Therefore, the value of the expression (a³b-2 + c)² when a = -2, b = 3, and c = -5 is 961.
