25×125×5×2×4×8=(25×4)×(125×8)×(5×2)=100×1000×10=1000000
25×1.6=25×4×0.4=100×0.4=40
125×72=125×8×9=1000×9=9000
47×56+47×47=47×(56+47)=47×(100+3)=4700+47×3=4741
99×45=45×(100-1)=4500-45=4455
101×45=45×(100+1)=4500+45=4545
9.9×45+4.5=9.9×45+0.1×45=(9.9+0.1)×45=10×45=450
101×45-45=(101-1)×45=100×45=4500
56×11=560+56=616
37×?,记住有37×3=111
.50*2+.125*8+.25*4+.20*5+B=
(-125)*(-25)*(-5)*2*(-4)*(-8) =要简便算式
—125×(-25)+(—5)×(+2)×(—4)×(—8)
简便计算125×14×4×8×25×5×2?
(-125)*(-25)*(-5)*(+2)*(-4)*(-8) 要有过程,谢谢
25×8×125×4
8*4*25*125
25×4+125×8
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
25×125×4×8=?
.125*8+.25*4=
9,8,7,6 2,3,4,5 4,9,16,25 8,27,64,125
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)][log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)
(㏒2^125+㏒4^25+㏒8^5)×(㏒5^2+㏒25^4+㏒125^8) 计算我不太会,
(1)、[(4×8)×25-8]×125(2)、125又七分之五 ÷(-5)
(-5)×(-25)+125(-2)×0.8
怎样用简便方法计算432*2*125*25*5*4*8
432*2*125*25*5*4*8等于多少?用简便方法计算!
