a) 17,58 - 6,35 - 5,65
= 17,58 - ( 6,35 + 5,65 )
= 17,58 - 12
= 5,58
b) ( 1,1 x 1,2 x 1,3 x 1,4 x 1,5 x 1,6 ) x ( 1,25 - 0,25 x 5 )
= ( 1,1 x 1,2 x 1,3 x 1,4 x 1,5 x 1,6 ) x ( 1,25 - 1,25 )
= ( 1,1 x 1,2 x 1,3 x 1,4 x 1,5 x 1,6 ) x 0
= 0
a) = 17,58-(6,35+5,65)
= 17,58-12
= 5,58
b) = 0 vì 1,25-0,25x5=0
