A kilobyte is 210. A megabyte is 220 bytes. How many kilobytes are in a megabyte? Use the exponent rule for division to find your answer and give your answer in exponential form
a kilobyte is 2^10 bytes
and you're converting 1 megabyte to kilobyte.
converting units that you learned in science class
(1 megabyte / 1) (2^20 bytes / 1 megabyte) (1 kilobyte / 2^10 bytes)
megabyte and bytes cancels out and you're left with
2^20 kilobyte / 2^10 = 2^10 kilobyte
hope this helps
Answer:
\(2^{10} kilobyte\) are in a 1 megabyte.
Explanation:
Given : 1 kilobyte = \(2^{10} bytes\)..(1)
1 mega bytes = \(2^{20} bytes\)..(2)
To find: 1 megabytes = ? kilobytes
Solution:
Divide (1) and (2) :
\(\frac{1 kilobyte}{1 megabyte}=\frac{2^{10} bytes}{2^{20} bytes}\)
Using identuty :\(\frac{a^m}{a^n}=a^{m-n}\)
\(\frac{1 kilobyte}{1 megabyte}=2^{10-20}=2^{-10}\)
\(\frac{1 kilobyte}{2^{-10}}=1 megabyte\)
\(1 megabyte=2^{10} kilobyte\)
\(2^{10} kilobyte\) are in a 1 megabyte.
