You can enter this as sqrt(7), or as 7^(1/2). This is because Edfinity understands functions like sqrt (square root) and also knows that roots can be taken using exponents. Note, exponents can be entered with a ^ (caret), which is above the 6 on your keyboard. You could also compute on your calculator and enter the value you get. When entering decimal approximations like this, be sure to give at least five significant digits (significant digits start with the first non-zero digit). So, 2.64 will be marked wrong but 2.6457 will be marked right.
