#v=sqrt[(6.67*10^-11*6*10^24)/(7300*10^3)]~~7402.70221#

Explanation:

Note that

#color(red)[x^n*x^m=x^(n+m)]#

#color(red)[x^n/x^m=x^n*x^-m=x^(n-m)]#

#v=sqrt[(6.67*10^-11*6*10^24)/(7300*10^3)]#

#v=sqrt[(6.67*6*10^(24-11))/(73*10^5)]#

#v=sqrt[(6.67*6*10^(13)*10^-5)/(73)]#

#v=sqrt[(6.67*6*10^(13-5))/(73)]#

#v=sqrt[(6.67*6*10^(8))/(73)]#

#v=sqrt[(40.02*10^(8))/(73)]#

#v~~sqrt[(0.548*10^(8))]#

#v~~7402.70221#

in the last equation you must use calculator to get the exact value because there are complex numbers.
