50\times 10^{3}r^{2}=9\times 10^{9}\times 80\times 10^{66}\left(-6\right)\times 10^{-6}
Променливата r не може да биде еднаква на 0 бидејќи делењето со нула не е дефинирано. Помножете ги двете страни на равенката со r^{2}.
50\times 10^{3}r^{2}=9\times 10^{75}\times 80\left(-6\right)\times 10^{-6}
За да множите степени со иста основа, соберете ги нивните степенови показатели. Соберете ги 9 и 66 за да добиете 75.
50\times 10^{3}r^{2}=9\times 10^{69}\times 80\left(-6\right)
За да множите степени со иста основа, соберете ги нивните степенови показатели. Соберете ги 75 и -6 за да добиете 69.
