A = \(\dfrac{8\times12\times32+4\times27\times24+96\times41}{16\times48-48\times9+4\times3\times12}\)
A = \(\dfrac{96\times32+96\times27+96\times41}{16\times48-48\times9+48\times3}\)
A = \(\dfrac{96\times\left(32+27+41\right)}{48\times\left(16-9+3\right)}\)
A = \(\dfrac{96\times100}{48\times10}\)
A = \(\dfrac{20}{1}\) \(\times\) \(\dfrac{48\times10}{48\times10}\)
A = 20

Lời giải:
a. $=(327-27)+(216-16)+600=300+200+600=1100$
b. $=16\times 48+16\times 24+16\times 28$
$=16\times (48+24+28)=16\times 100=1600$

( 48 + 32 + 56 ) : 8
= 48 : 8 + 32 : 8 + 56 : 8
= 6 + 4 + 7 = 10 + 7 = 17
= 16 + 14 x 32 +8 x 48
= 20 x 40 x 48
= 38400
