#7.0 xx 10^(-18)#

Explanation:

We're going to put this into standard form.
First step: count how many figures we have to move past to put the decimal point behind the #7#. In this case it is #18#.
Then check which way we've moved the decimal point.
To the right #= -18#, to the left# = +18#.
Since it is to the right, we're going to use #-18#.
Therefore, our answer is going to be #7.0 xx 10^(-18)#.
