\(\frac{23^{10}-23^{11}}{23^{11}+21.23^{10}}=\frac{23^{10}\left(1-23\right)}{23^{10}\left(23+21\right)}=-\frac{22}{44}=-\frac{1}{2}\)
mk lam cho
=2310(1-23)/2310(23-21)=-22/2=-11
tk nha
\(\frac{23^{10}-23^{11}}{23^{11}+21\cdot23^{10}}\)
\(=\frac{23^{10}\left(1-23\right)}{23^{10}\left(23+21\right)}\)
\(=\frac{22}{44}\)
\(=\frac{1}{2}\)
\(\frac{23^{10}-23^{11}}{23^{11}+21.23^{10}}\)
\(=\frac{23^{10}\left(1-23\right)}{23^{10}\left(23+21\right)}\)
\(=\frac{-22}{44}\)
\(=\frac{-1}{2}\)
