Rút gọn A
rút gọn phân số:
\(\frac{-1997.1996+1}{\left(-1995\right).\left(-1997\right)+1996}\)
Rút gọn
\(\frac{-1997.1996+1}{-1995.\left(-1997\right)+1996}\)
rút gọn các phân số sau
a) :\(\frac{\left(-5\right)^3.40.4^3}{135.\left(-2\right)^{14}.\left(-100\right)^0}\)
b) \(\frac{-1997.1996+1}{\left(-1995\right).\left(-1997\right)+1996}\)
Rút gọn phân số
