Answer:
5+(23xN)
I think this is right. Sorry if I'm wrong.
We can solve this in many ways, let's try this one.
T∧2 = 4 pi∧2 * a∧3 / GM First we will multiply whole equation with variable( or parameter) M and get
M * T∧2 = 4 pi∧2 * a∧3 / G After that we will divide whole equation with variable ( or parameter ) T∧2 and get
M = 4 pi∧2 * a∧3 / G * T∧2
This is correct answer
Good luck!!!
