The answer is #1/36000000#.

Explanation:

Using the Order of Operations or PEMDAS, we evaluate the expression in the parenthesis first. #6 * 10^3# gives us 6000. #6000^-2# can be rewritten or simplified as #1/(6000^2)#. (You can see this by using the Law of Exponents of Subtraction. #6000^-2# can be written as #6000^(0-2)# = #(6000^0)/(6000^2)# = #1/6000^2)#. Then, simplify the denominator and the resulting fraction is #1/36000000#.
