Since 1 nanometer = 1x10^-9 meter, then, use the conversion factor:

Multiply the thickness of the sheet of paper measured in meters times the conversion factor:

Rewrite 0.00005 in scientific notation by moving the point 5 places to the right:

The thickness of the sheet of paper, is:

Use the laws of the exponents to rewrite 10^-5/10^-9:

Rewrite 5x10^4 nm by moving the point 4 places to the right:

Therefore, the thickness of a sheet of paper is 50,000 nm.
