Chemistry Question its a operation basic one?

Question

(7.77times10cubed kg)(9.76times10to the 9th m) all divided by (8.67 times 10 to the 9th s)(3.43 times 10 cubed s)

Answer 1

(7.77x10^3)(9.76x10^9)/(8.67x10^9)(3.43x...

Good news is, all the "x10^n" cancel out because they match top and bottom, so...

(7.77*9.76)/(8.67*3.43)=2.55kg*m/s^2

Answer 2

First divide all the units:

kg*m/(s*s)=kg*m/(s^2)=m*a=ma=f because of newtons law f=ma and m is kg, a is m/s^2.

now, multiply the numbers in the numerator:

7.77*9.76=75.8352

10^3*10^9=10^12

and the denoms:

8.67*3.43=29.7381

10^9*10^3=10^12

The 10^12's cancel, leaving:

[75.8352]/[29.7381]=2.5501 newtons
