posted by Hannah .
this is my last question for the whole assigment and im soo glad!!!
(9465 + 45 - 9.9) 8.1 X 10^6
i got 76950.e6
it said it was half right and said check your number of sig figs
the 8.1 will limit the answer to two sig figures. The answer cannot be more precise than the least precise number.

Nope. 77000e6 or 7.7e10
