1. the speed of light is 8.0x^8m/s in standard form that is?
2. the average size of a virus is 2x 10^10 nanometers in diameter.
how to write the number(s) given scientific notation in standard form.
thank you

If a number has a negative exponent, move the decimal to the left to convert
to Standard form. If the exponent is positive, move the decimal to the right.
1. 8.0*10^8 = 800,000,000 m/s.
We moved the decimal 8 places to the right.
2. 2.*10^10 = 0.0000000002 nm.
We moved the decimal 10 places to the left.
