Subtract the product of three and six from thirty-five.

17

Step-by-step explanation: Product means the result of a multiplication, so you have to multiply three and six. Next, put that in parenthesis because it is the first expression to solve. Now, you subtract the product from thirty-five, meaning you take away eighteen (the product of 3 and 6) from thirty-five. The final equation will look like 35-18. The answer to that will be 17.

correct answer:

i^31 = -i
