Question

I really need help with this. Please explain how you get the answer.

Answer 1

So firstly, substitute the values into the expression:
`3^3-2*5^2-3*3^3+(-3)^4`

Next, solve the exponents:
`27-2*25-3*27+81`

Next, solve the multiplications:
`27-50-81+81`

Lastly, combine everything, and your answer will be -23.
