Answer:
So in decimal [tex]7.8\times 10^{-2}mm[/tex] will be equal to 0.078 mm
Step-by-step explanation:
We have given the width of the pixel on a smart phone is [tex]7.8\times 10^{-2}mm[/tex]
We have to write this into decimal form
[tex]10^{-2}=\frac{1}{100}[/tex]
So for converting [tex]7.8\times 10^{-2}mm[/tex] into decimal we have to divide 7.8 by 100
So [tex]7.8\times 10^{-2}mm[/tex] = [tex]\frac{7.8}{100}=0.078mm[/tex]
So in decimal [tex]7.8\times 10^{-2}mm[/tex] will be equal to 0.078 mm
