Megabytes in digital photos

A color photograph taken with a digital camera is converted into a digital format using 4. 10⁰ bytes per pixel. Photographs taken with the camera each have 2.2. 10⁶ pixels.

How many bytes are there in one photo?

Write your answer in scientific notation.

Correct answer:

x =  8800000

Step-by-step explanation:

$$\begin{gathered} p=4\cdot 10^0=4 \\ n=2.2\cdot 10^6=2200000 \\ x=p\cdot n \\ x=4\cdot 10^0\cdot 2.2\cdot 10^6 \\ x=4\cdot 2.2\cdot 10^{0+6} \\ x=8.8\cdot 10^6 \\ x=8.8MB \\ x=p\cdot n=4\cdot 2200000=8800000 \end{gathered}$$
