Question

Write the following numbers in decimal form. (Note: Some of these numbers have been rounded.)

Answer 1

Answer:

So in decimal  $7.8\times 10^{-2}mm$ will be equal to 0.078 mm

Step-by-step explanation:

We have given the width of the pixel on a smart phone is $7.8\times 10^{-2}mm$

We have to write this into decimal form

$10^{-2}=\frac{1}{100}$

So for converting $7.8\times 10^{-2}mm$ into decimal we have to divide 7.8 by 100

So $7.8\times 10^{-2}mm$ = $\frac{7.8}{100}=0.078mm$

So in decimal  $7.8\times 10^{-2}mm$ will be equal to 0.078 mm
