Working with units and exponents

Final answer should be given in simplest form!

N= kgm/s²

j = Nm = kgm²/s²

w = j/s

1.    2.5x10¹² m/s² * 3x10¹⁰s = 7.5m/s

2.    2.75x10⁴ m/s : 3.1x10³s = 8.9m/s²      

3.    2.05x10³ m/s² * 2.5X10^-4kg = 0.5N

4.    10.5x10⁵N : 4.3x10¹⁰m/s² = 2.44kg

5.    15.3x10^-3N : 4.5x10^-2kg = 0.34m/s²

6.    5.4N * 4.5x10⁵m = 2.4*10⁶J

7.    0.5kg/m³ * 4.34m³ = 2.17kg

8.    20.4x10^-5 j : 4.4x10^-3m = 4.6*10^-2 N

9.    3x10⁸m/s * 5.45x10⁶s = 1.635*10¹⁵m/s²

10. 40.6x10^-3j : 4.2x10^-5N = 9.6667*10²m

11. 2x10³ j : 5w = 400s

12. 2x10⁵w * 5x10⁷s = 10¹³J

13. 5x10³kg * 2.5x10^-3m/s = 1.025*10kgm/s

14. 2x10³j : 5w = 40s
