Question

tính nhanh:

512.[2-128]-128.[-512]

Answer 1

   512.(2-128)-128.(-512)

= [512.(2-128)]-[128.(-512)

= - 64512 - (- 65536)

= - 64512 + 65536

= 1024

Answer 2

\(512.(2-128)-128.(-512)\)

\([512.(2-128)]-[128.(-512)]\)

\(-64512-(-65536)\)

\(-64512+65536\)

\(1024\)

Answer 3

512.[2-128]-128.[-512]

=512.[-126]-128.[-512]

=[-512].126-128.[-512]

=[-512].[126-128]

=[-512].[-2]

=11024
