Write each answer as a power of 2.
15. Computer capacity is often measured in bits and bytes. A bit is the smallest unit, a 1 or 0 in
the computer’s memory. A byte is 2 3 bits. A megabyte (MB) is 2 20 bytes. How many bits are
in a megabyte?




16. A gigabyte (GB) is 210 megabytes. How many bytes are there in a gigabyte?
