aaronq · Answer

the exponent $10^x$ implies that the decimal point is moving:
:left $\leftarrow$ when x is positive and left when x is negative.

for example,

a) $78.9*10^{-13} g$, x=negative.
the decimal point will move 13 spaces to the left. 
    000000000000079.8  $\rightarrow$   0.00000000000789
