Answer:
To do this question, we must first convert Pi to a decimal form, as shown below:
Pi = 3.14
So then our equation becomes:
3.14 x 36 - 16
We still need to remember PEMDAS.
Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
So according to PEMDAS, we need to do 3.14 x 36, which equals 113.04
Now we have to do:
113.04 - 16 = 97.04
Our answer is 97.04

Are you sure you've copied down the original problem exactly as given? i38 = 38i can't be simplified. Perhaps you meant i^38, which is a different matter.
Note that i^38 = i^32 * I^4 * I^2.
Note that i^0, i^4, i^8, etc., all equal 1. Therefore,
i^38 = (1)(1)i^2 = 1*(-1) = -1 (answer)
Answer:
