Step-by-step explanation:
[tex]\frac{11.4\times\:10^{20}}{2\times\:10^{13}}\\\\\mathrm{Cancel\:}\frac{11.4\times\:10^{20}}{2\times\:10^{13}}:\quad \frac{10^7\times \:11.4}{2}\\\\\mathrm{Factor}\:10^7:\quad 2^7\times\:5^7\\=\frac{2^7\times\:5^7\times\:11.4}{2}\\\\\mathrm{Cancel\:the\:common\:factor:}\:2\\=5^7\times\:2^6\times\:11.4\\\\5^7=78125\\\\2^6\times\:78125\times\:11.4\\\\2^6=64\\\\=78125\times\:64\times\:11.4\\\\=57000000\\\\= 5.7 \times 10^7[/tex]
