The powers of 2 ( 20=1 , 21=2 , 22=4 , etc) arise frequently in computer science. (For example, you may have noticed that storage on smartphones or USBs come in powers of 2, like 16 GB, 32 GB, or 64 GB.) Use np. arange and the exponentiation operator ** to compute the first 30 powers of 2, starting from 2^0.
