\(\left(-64\right).125=x^3\)
\(\Rightarrow x^3=\left(-64\right).125\)
\(\Rightarrow x^3=-8000\)
\(\Rightarrow-20^3=-8000\)
\(\Rightarrow x_0=-20\)
Ta có:
\(\left|x_0+25\right|\)
\(=\left|-20+25\right|\)
\(=\left|5\right|\)
\(=5\)
\(\Rightarrow\left|x_0+25\right|=5\)
Ix-1I+Ix-2I+Ix+3I+.....+Ix-100I=2500
Giup em với a~~~
