làm nhanh giúp mình nhé!
So sánh
a) \(\left(\frac{1}{80}\right)^7\) với \(\left(\frac{1}{243}\right)^6\)
b) \(\left(\frac{3}{8}\right)^5\)với \(\left(\frac{5}{243}\right)^3\)
SO SÁNH
\(\left(\frac{1}{80}\right)^7va\left(\frac{1}{243}\right)^6\)
\(\left(\frac{3}{5}\right)^5va\left(\frac{5}{243}\right)^3\)
\(\frac{-22}{35}va\frac{-103}{177}\)
\(\frac{84}{-83}va\frac{-337}{331}\)
So sánh \(\left(\frac{1}{80}\right)^7\) với \(\left(\frac{1}{243}\right)^6\)
\(\left[x+\frac{1}{3}\right]+\left[x+\frac{1}{15}\right]+\left[x+\frac{1}{35}\right]+...+\left[x+\frac{1}{575}\right]\)
\(=11xx+\left[\frac{1}{3}+\frac{1}{9}+\frac{1}{27}+\frac{1}{81}+\frac{1}{243}\right]\)
