Tính a) 2.(-25).(-4).50 b) 16.50.(-25).(250) c) (-167).(-83) +167.17 -33 d) (135 -35).47

* Hướng dẫn giải

a) $2.\left(-25\right).\left(-4\right).50=10000$

b) $\mathrm{16.50.}\left(-25\right).\left(-250\right)=5000000$

c) 

$\begin{array}{l}\left(-167\right).\left(-83\right)+167.17-33=167.83+167.17-33\\ =167.\left(83+17\right)-33=167.100-33=1667\end{array}$

d) 

$\begin{array}{l}\left(135-35\right).47-53.\left(-48-52\right)=100.47-53.\left(-100\right)\\ =100.47+53.100=100.\left(47+53\right)=100.100=10000\end{array}$
