Last year a large trucking company delivered 9.0 × 105 tons of goods with an average value of $17,000 per ton. what was the total value of the goods delivered? write the answer in scientific notation.

I don't really understand the question but I'll answer how I'm reading it. 

9 x 105 = 945
945 x 17000 = 16,0650,000

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
