The expression [2³ x (225 +9)] - 33 can be simplified to 2³ x 234 - 33. To evaluate this expression, we can begin by calculating 2³ x 234. 2³ is equal to 8, so 8 x 234 = 1872. Subtracting 33 from 1872 gives us a result of 1839. Therefore, the expression [2³ x (225 +9)] - 33 can be simplified to 1839.
