2**4 means two to fourth: 2*2*2*2=16 2**5 means the fifth power of two: 32 9**(1/2) is the square root, so it is 3

Well, Python applies operator precedence just like the one in lower primary school 'BODMAS' Hence in our example, the arithmetic in the parenthesis is computed first. I.e (5-1)=4 Then 2**4 is 2 raised to the power of 4, resulting to 16. 😉
