✔ 最佳答案
( 3.2 ) x [-(0.17-1.98) + (-3.6) - (4.71)]
=( 3.2 ) x [-(-1.81) + (-3.6) - (4.71)]
=( 3.2 ) x (1.81 - 3.6 -4.71)
=3.2 x (-6.5)
=-(3.2x6.5)
=-20.8

( 3.2 ) x [-(0.17-1.98) + (-3.6) - (4.71)]
=( 3.2 ) x[-(-1.81) + (-3.6) - (4.71)]
=( 3.2 ) x(1.81-3.6-4.71)
=3.2x(-6.5)
=-20.8

( 3.2 ) x [-(0.17-1.98) + (-3.6) - (4.71)]
=3.2 x [-(-1.81)+(-3.6)-(4.71)]
=3.2 x [1.81+(3.6)-(4.71)]
=3.2 x [1.81-3.6-(4.71)]
=3.2 x [(-1.79)-(4.71)]
=3.2 x (-6.5)
=20.86

( 3.2 ) x [-(0.17-1.98) + (-3.6) - (4.71)]

=( 3.2 ) x [-(-1.81) + (-3.6) - (4.71)]

=( 3.2 ) x (1.81 - 3.6 -4.71)

=3.2 x (-6.5)

=-(3.2x6.5)

=-20.8
依條根本唔係中一既數學題!易到爆!

( 3.2 ) x [-(0.17-1.98) + (-3.6) - (4.71)]
=( 3.2 ) x [-(-1.81) + (-3.6) - (4.71)]
=( 3.2 ) x (1.81 - 3.6 -4.71)

=-20.8
2007-11-04 5:48 am
=(3.2)x[-(-1.81)-3.6-4.71]
=(3.2)x(1.81-8.31)
=(3.2)x(-6.5)
=-20.8
2007-11-04 5:47 am
( 3.2 ) x [-(0.17-1.98) + (-3.6) - (4.71)]
=3.2x[1.81+(-3.60)-(4.71)]
=3.2x[5.41-4.71]
=3.2x0.7
=2.24

The answer is 2.24

2007-11-03 21:49:07 補充:
the answer should be-20.8
參考: me
2007-11-04 5:46 am
=3.2 x ( - 0.17 + 1.98 - 3.6 - 4.71 )
=3.2 x ( - 6.5 )
= - 20.8
