An electron micrograph of a mitochondrion has an image length of 7.2 cm7.2\text{ cm}7.2 cm. The actual length of the mitochondrion is 1.8×10−6 m1.8 \times 10^{-6}\text{ m}1.8×10−6 m.
Calculate the magnification used to view the mitochondrion. Give your answer in the form a×10na \times 10^na×10n, where 1≤a<101 \le a < 101≤a<10 and nnn is an integer.
Use the formula: magnification=size of imagesize of real object\text{magnification} = \frac{\text{size of image}}{\text{size of real object}}magnification=size of real objectsize of image
