Question

tính giá trị biểu thức :


A =  2013 x 14 + 1998 + 2010 x 2012

       2025 + 2025 x 2012 - 2025 x2013

Answer 1

\(A=\frac{2013\cdot14+1998+2010\cdot2012}{2025+2025\cdot2012-2025\cdot2013}\)

\(A=\frac{2013\cdot14+1998+2010\cdot2012}{2025\left(1+2012-2013\right)}\)

\(A=\frac{2013\cdot14+1998+2010\cdot2012}{2025\cdot0}\)

\(A=\frac{2013\cdot14+1998+2010\cdot2012}{0}\)

\(A=0\)
