Gravitational potential energy is given by equation U = -GMm/r where G is gravitational constant, M and m are masses of two objects and r is the distance betwe...

2^2x - 6(2^x ) + 5 = 0let y = 2^xy² - 6y + 5 = 0(y-5)(y-1) = 0 y=5, y=12^x = 5, therefore, x = log₂5 = 2.32 (3 s.f.)2^x = 1, therefo...
