Question

A=(156,2+3,8-17,5+252,5-197)x(0,2-2:10)x2001

 

Answer 1

\(A=\left(156,2+3,8-17,5+252,5-197\right)\times\left(0,2-2\div10\right)\times2001\)

\(\Rightarrow A=\left(156,2+3,8-17,5+252,5-197\right)\times\left(0,2-0,2\right)\times2001\)

\(\Rightarrow A=\left(156,2+3,8-17,5+252,5-197\right)\times0\times2001\)

\(\Rightarrow A=0\)

Answer 2

A = (156,2+3,8-17,5+252,5-197)×(0,2-0,2)+2001 A=(156,2+3,8-17,5+252,5-197)×0×2001 A=0

Answer 3

\(A=(156,2+3,8-17,5+252,5-197)\cdot(0,2-\frac{2}{10})\cdot2001\)

\(=(156,2+3,8-17,5+252,5-197)\cdot(0,2-0,2)\cdot2001\)

\(=(156,2+3,8-17,5+252,5-197)\cdot0\cdot2001\)

\(=(156,2+3,8-17,5+252,5-197)\cdot0\)

\(=0\)

Vậy A = 0
