(63+64)x5=635 (228+229)x5=2285 (1730+1731)x5=17305 (_______+_______)x5=__________
(63+64)x5=635 (228+229)x5=2285 (1730+1731)x5=17305 (_______+_______)x5=__________
(63+64)x5=635
(228+229)x5=2285
(1730+1731)x5=17305
(_17999+18000__)x5=179995__________
公式为
(X+X+1)*5=(2X+1)*5=10X+5=X5
任何两个相邻的数相加都成立
这个题错了吧》?
17999 18000乘5=179995
