\(N=\frac{6}{10^{2015}}+\frac{8}{10^{2016}}=M=\frac{8}{10^{2015}}+\frac{6}{10^{2016}}\)
Hk tốt
k nhé
Ta có :N= \(\frac{6}{10^{2015}}+\frac{8}{10^{2016}}=\frac{6}{10^{2015}}+\frac{6}{10^{2016}}+\frac{2}{10^{2016}}\)
M=\(\frac{8}{10^{2015}}+\frac{6}{10^{2016}}=\frac{6}{10^{2015}}+\frac{6}{10^{2016}}+\frac{2}{10^{2015}}\)
Ta Xét: \(\frac{2}{10^{2016}},\frac{2}{10^{2015}}\)
Vì 102016>102015
Nên: \(\frac{2}{10^{2016}}< \frac{2}{10^{2015}}\)
Do đó : N<M
