To evaluate the expression (8 + 1)3 - 6 when t = 2, we can substitute t = 2 into the expression and perform the necessary calculations step by step.
Given expression: (8 + 1)3 - 6
Substitute t = 2 into the expression:
(8 + 1)3 - 6 = (9)3 - 6
Now, simplify the expression:
(9)3 - 6 = 27 - 6
Finally, calculate the value:
27 - 6 = 21
Therefore, when t = 2, the value of the expression (8 + 1)3 - 6 is 21.
