Final answer:
To evaluate the expression 10*(-2x)3 for x = –1, substitute the value of x into the expression and perform the necessary operations. The value of the expression is 80.
Step-by-step explanation:
To evaluate the expression 10*(-2x)3 for x = –1, we substitute the value of x into the expression and perform the necessary operations.
Step 1: Substitute x = –1 into the expression:
10*(-2*(-1))^3
Step 2: Simplify the expression inside the parentheses:
10*(2)^3
Step 3: Evaluate the exponent:
10*(8)
Step 4: Perform the multiplication:
80
Therefore, the value of the expression 10*(-2x)3 for x = –1 is 80.
