Answer:

#.0014#

Explanation:

There's a neat trick for this. You just look at your starting value, #1.4#, and you shift the decimal over 3 places. You know which direction to move it to by looking at the exponenet and checking if it is negative (-) or positive (+). In this case #10^-3# is risen to a negative nmber, meaning the value of #1.4# should decrese, which means moving to decimal point to the left, like how the numbers on the left on a timeling are the more negativenumbers.

Now we have 0.0014, which we got by shifting the decimal to the left #3# places.
