Scientific notation ? Please help

(5.55 x 10^15) x (8.88 x 10^18)

Explanation:

I first take back the numbers to their original forms that is to say (5.55×10^15) = 5550000000000000 and (8.88×10^18) = 8880000000000000000 therefore the difference of the two will be 887445 which is notated to (8.87445×10^5)

(8.87445×10^5)
