Gỉai nhanh giúp mình nha mn. Cảm ơn trước nha
Tìm x bt:
\(\left[x+\frac{1}{1.2}\right] +\left[x+\frac{1}{2.3}\right]+\left[x+\frac{1}{3.4}\right]+...+\left[x+\frac{1}{99.100}\right]=100x\)
cái [] là trị tuyệt đối nhé
a, \(2^x+2^{x+1}+2^{x+2}=112\)
b,\(|x+\frac{1}{1.2}|+|x+\frac{1}{2.3}|+|x+\frac{1}{3.4}|+...+|x+\frac{1}{99.100}|=100x\)
\(\left|x+\frac{1}{1.2}\right|+\left|x+\frac{1}{2.3}\right|+\left|x+\frac{1}{3.4}\right|+...+\left|x+\frac{1}{99.100}\right|=100x\)
Tìm \(A=\frac{1}{1.2}+\frac{1}{2.3}+\frac{1}{3.4}+...+\frac{1}{99.100}\)
