Substituting s = 3 and t = 2 into the expression yields a value of 244.
To evaluate the expression 2(s + t)^3 - 6 when s = 3 and t = 2, substitute these values into the expression:
2(3 + 2)^3 - 6
First, evaluate the expression within the parentheses:
2(5)^3 - 6
Calculate the cube of 5:
2(125) - 6
Multiply 2 by 125:
250 - 6
Subtract 6 from 250:
244
Therefore, when s = 3 and t = 2, the value of the expression 2(s + t)^3 - 6 is 244.
