tolong bantuanya buat bsok

[tex] \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 [/tex]
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...
