Help with Algebra equation
In each problem, use the 5 digits, along with the symbols + – × ÷ ( ) as necessary, to make an expression equal to 2011. No other symbols are allowed. For example, for 4, 5, 7, 7, 8, the answer would be 7^4– 5 × 78 = 2011.

A. 1 2 3 5 8

B. 1 3 4 8 9

C. 1 3 6 7 8

D. 1 4 5 6 7

You are allowed to use a number as an exponent, and 7^4 - 5 x 78 is simply an example, the problem requires you to perform the same action for the provided sets

Sorry, you fail. According to the question, the symbol ^ is not allowed. (Evilgrin)

But wouldn't $\displaystyle 7^4- 5\times 78$ count?
