48 x 27 + 48 + 96 x 36
= 48 x (27 + 1) + 48 x 72
= 48 x 28 + 48 x 72
= 48 x (28 + 72)
= 48 x 100
= 4800 .

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

48 x 27 + 48 + 96 x 36

A) 4,29 x 1230 - 429 x 2,3
= 429 x 12,3 - 429 x 2,3
= 429 x ( 12,3 - 2,3 )
= 429 x 10
= 4290
B) 30 - 15 + 36 - 18 + 42 - 21 + ... + 96 - 48 + 102 - 51
= ( 15 + 15 ) - 15 + ( 18 + 18 ) - 18 + ... + ( 48 + 48 ) - 48 + ( 51 + 51 ) - 51
= 15 + 18 + 21 + ... + 48 + 51
= [( 51 - 15 ) : 3 + 1] x ( 15 + 51 ) : 2
= [36 : 3 + 1] x 66 : 2
= [12 + 1] x 33
= 13 x 33
= 429
