$frac{ {2}^{9} times {3}^{5} times {7}^{7} }{ {4}^{5} times {21}^{4} } = frac{ {2}^{9} times {3}^{5} times {7}^{5} times {7}^{2} }{ {2}^{10} times {21}^{4} } = frac{ {21}^{5} times {7}^{2} }{2 times {21}^{4} } = frac{21 times {7}^{2} }{2} = 514.5$
semoga membantu dan maaf jika salah

2/9 =512
3/5 = 243
7/3 = 343
Hasil ke-1= 42.674.688
4/5 = 1.024
21/4 = 194.481
Hasil ke-2= 199.148.544
hasil 1 dibagi hasil 2 =
42.674.688 / 199.148.688 = 0, 2142857143

Semoga benar ya…
