$m1 = \frac{fr}{ \gamma m2} = \frac{64032 \times {10}^{ - 5} \times 5 }{6.67 \times {10}^{ - 11} \times 4 \times {10}^{9} } = \\ \frac{48 \times {10}^{3} + \times {10}^{5} }{ {10}^{ - 2} } = 48 \times 10 ^{10}$

$5 \times {10}^{ - 2} + 0.6 \times {10}^{ - 2} + 0.01 \times 10 ^{ - 2} = \\ 5.61 \times {10}^{ - 2}$

5.61*10^-2

$( \frac{4a}{b} + \frac{9b}{a} + 12) = \\ \frac{4 {a}^{2} }{ab} + \frac{9{b}^{2} }{ab} + \frac{12ab}{ab} = \\ \frac{4 {a}^{2} + 12ab + 9 {b}^{2} }{ab}$

$\frac{4 {a}^{2} + 12ab + 9 {b}^{2} }{ab} \times \frac{ab}{3b \times 2a} = \frac{ {(2a + 3b)}^{2} }{3b + 2a} = 2a + 3b$
