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.
