Primcipal 739.30 Total = 778.90
Found by trial and error. I tried using equations but when you have TWO unknowns, it's (I think) impossible.
<span>\[(2\sqrt{5}+3\sqrt{7})(2\sqrt{5}+3\sqrt{7})\]</span>
<span>None of the above. The mass does not change if you change the gravitational constant (moving to Jupiter or Moon), only the weight changes. By cutting it in half you decrease the mass, you do not increase it.</span>
