Oh i hope you listened to the only one who was actually correct :) ... you have to follow the order of operations! PEMDAS ( parenthesis/exponents/ multiply/divide/add/then subtract.

15 - 2^3 / 4 , first do 2^3 = 2*2*2 = 8.... then divide, 8 / 4 = 2.... lastly subtract 15 - 2 = 13.

The answer is totally 13

Is it written (15-2)3 / 4 or is the third power above the 2. Ifthe power number is above a single number, that number is multiplied three times that subtracted. The answer could be

15 - 2x2x2 = 7 Divided by 4 equals 1-3/4 or 1.75.

15 minus 2 to the 3rd power divided by 4

15 - ( 2 to the 3rd power ) divided by 4

15 - ( 2x2x2 ) / 4 = ?

(15 - 8) / 4 = ?

7 / 4 = 1.75

15 minus 2 to the 3rd power divided 4

I believe you're asking for 15 - 2^3/4

This equals 15 -8/4 = 15 - 2 = 13
