Homework Statement



2.573x10^13 x 6.58x10^-5 x 7.0732x10^11




The Attempt at a Solution


would you round up the answer to 120 initially after multiplying?

here's my answer 120x10^19=1.20x10^17

I would round-off AFTER I get the final result for the power of ten.

BTW, your final answer is incorrect.

120x1019 = (1.20x102)x1019 = ___ ?
