Question

How to write 0.0058 in scientific notation

Answer 1

move decimal between 5 and 8 which mean you moved it to the right 3 times and your answer will be 5.8 x 10 ^-3 the exponent is a negative because there was zeros in the beginning.

Answer 2

5.8 x 10^-3

This is because you have to move the decimal so there is no non zero digits left in the decimal point and if the number of decimal places you move will be the exponent on the "10". If you move the decimal to the right it will be a negative and if you move it to the left it will be a positive.
