36 x 532 + 64 x 532
=(36+64)x532
= 100x532
=53 200
245 x 327 - 245 x 26 - 245
=245x327-245x26-245x1
=245x(327-26-1)
=245x300
=73 500

A = \(\dfrac{27\times327\times512\times213\times57}{54\times327\times512\times213\times57}\)
A = \(\dfrac{27}{54}\)
A = \(\dfrac{1}{2}\)

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

53 x 4 x 3 x 25 = 53 x ( 4 x 25 ) x 3
= 53 x 100 x 3
= 15900
327 x 73 + 27 x 327 = 327 x ( 73 + 27 )
= 327 x 100
= 32700

a) \(52\times4\times3\times25\)
\(=\left(52\times3\right)\times\left(4\times25\right)\)
\(=156\times100\)
\(=15600\)
b) \(327\times73+27\times327\)
\(=327\left(73+27\right)\)
\(=327\times100\)
\(=32700\)
