a: \(32684+41325+316+675\)
\(=\left(32684+316\right)+\left(41325+675\right)\)
\(=33000+42000=75000\)
b: \(25\cdot18\cdot4\cdot2\)
\(=18\cdot2\cdot\left(25\cdot4\right)\)
\(=36\cdot100=3600\)
c: \(19\cdot81+19+18\cdot19\)
\(=19\left(81+1+18\right)\)
\(=19\cdot100=1900\)
A, 32684 + 41325 + 316 + 675
=(32684+316)+(41325+675)

a, 32684 + 41325 + 316 + 675
= (32684 + 316) + (41325 + 675)
= 33 000 + 42 000
= 75 000
b, 25 \(\times\) 18 \(\times\) 4 \(\times\) 2
= (25 \(\times\) 4) \(\times\) (18 \(\times\) 2)
= 100 \(\times\) 36
= 3600
= 24 x 427 + 24 x 573
= 24 x (427 + 573)
= 24 x 1000
= 24000
8 x 427 x 3 + 6 x 573 x 4
= 8 x 3 x 427 + 6 x 4 x 573
= 24 x 427 + 24 x 573
= 24 x (427 + 573)
= 24 x 1000
= 24000
2008 x 867 + 2009 x 133
= 2008 x 867 + 2008 x 133 + 133
= 2008 x (867 + 133) + 133
= 2008 x 1000 + 133
= 2008133
\(a,8\times427\times3+6\times573\times4\)

\(b,6\times1235\times20-5\times235\times24\)
\(=120\times1235-120\times235\)
\(=120\times\left(1235-235\right)\)
