Answer 7

\[3^4+12\div3-(1-9)\]
Remember the order of operations: Brackets, Exponents, Division, Multiplication, Addition, Subtraction. When there is a conflict of what to do first, do them in order as they appear from left to right. So with this, that would be brackets first (1-9 equals -8), then exponents (3^4)=81, then division (12/3)=4. So what you're left with is 81+4+8 (remember that subtracting a negative number is the same as adding the positive) which would be 93.
