3.5×64＋6.5×36
简便运算,需要完整的过程.
3.5×64＋6.5×36简便运算,需要完整的过程.
3.5×64＋6.5×36
=3.5*64+（3.5+3）*36
=3.5*（64+36）+3*36
=350+108
=458
3.5×64＋6.5×36
=3.5*64+(3+3.5)*36
=3.5*64+3.5*36+3*3.6
=3.5*（64+36）+3*36
=350+108
=458
3.5×64＋6.5×36
=3.5*(36+28)+6.5*36
=(3.5+6.5)*36+3.5*28
=10*36+0.5*7*4*7
=360+2*7*7
=360+98
=458
3.5×64＋6.5×36
=3.5×64＋6.5×(100-64)
=650-3×64
=650-192
=458
