This problem is about combined operations. We have a square power, a subtraction and whole products.

To solve this we can use PEMDAS which is an strategy to remember the order of operations, that is, Parentheses, Exponents, Multiplication-Division, Addition-Subtraction, that's the right order to solve.-


9^2\cdot3\cdot1-3

According to PEMDAS, we solve the power first:


81\cdot3\cdot1-3

Then, we solve multiplications:


243-3

Finally, we subtract:


240Therefore, the given expression is equal to 240.

Just remember, PEMDAS dictates the right order to use operations.
