Thực hiện phép tính
a) A= 33(1-2/3)(1-2/5)...(1-2/99)
b) B=101+100+99+98+...+3+2+1 / 101-100+99-98+...+3-2+1
c) C=423134x846267-423133 / 423133x846267+423134
A = \(\frac{101+100+99+98+...+3+2+1}{101-100+99-98+...+3-2+1}\)
B =\(\frac{3737\cdot4343\cdot37}{2+4+6+...+100}\)
\(A=\frac{101+100+99+98+...+3+2+1}{101-100+99-98+...+3-2+1}\)
\(A=\frac{\left(\frac{101-1}{1}+1\right)\left(\frac{101+1}{2}\right)}{\left(\frac{101-1}{2}+1\right)\left(\frac{101+1}{2}\right)-\left(\frac{100-2}{2}+1\right)\left(\frac{100+2}{2}\right)}=\frac{101.51}{51.51-50.51}\frac{101.51}{51}=101\)
