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

Verified Answer :

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.
