If x is 1, then 23x is 23, so we have 23-1=22 as the answer.
Well assuming this is the same math problem I had on my algebra quiz, it is meant to be written as "Evaluate 2^3x1 for x = 1"
With that being said, the answer is "8"
Step 1: Simplify. Turn 2^3x-1 into 2^3(1)
Step 2: Multiply exponents. 3 times 1 is 3 so it simply becomes 2^3
Step 3: Solve. Multiply 2 by itself three times. By doing this, you get 8!
2x2x2=8
