Here is a problems I am really having a trouble with:
The mass of Uranus is abou 8.7 x 10^22 metric tons. The mass of the sun is about 1.998 x 10^27 metric tons. About how many times the mass of Uranus is the mass of the sun? give your answer in the scientific motion.
The mass of the sun is about ____________ times the mass of Uranus. (round to the nearest thousandts as neeeded. Use scientific motion. Use the mulitpication symboy in the math palette as needed.)
Also: Simplify: (z^-7); (3c^-2d^3)^4 (m^8)^4 3^-2= (1)^2 (1)^-2 -3^2 (-3)^2
____ = __ __
n^9 3 3
If at all possible I need these solved by Friday, 3/5/10. Thank you very much.
