0.25*39+0.25简便计算0.25*39+0.25=0.25×（39+1）=0.25×40=100.25*39+0.25=0.25*(39+1)=0.25*40=100.25*39+0.25=0.25*（39+1）=0.25*40=1

简算：0.25×16×0.25快0.25×16×0.25=0.25×4×4×0.25=1×1=10.25=1/4所以1/4*16*1/4=1可以把16拆成4*4，结果是1.祝你好运！0.25×16×0.25=0.25×4×4×0.25=1×

x-0.25=0.25xx-0.25=0.25x化为x-0.25x=0.25即0.75x.=0.25所以x=0.25/0.75=1/3=0.3333333x/4=1/4x=1/3x-0.25=0.25x0.75x=0.25x=1/30.75

（49-0.25）/0.25+(46-0.25)/0.25+(43-0.25)/0.25+.+(1-0.25)/0.25等于多少?（49-0.25）/0.25+(46-0.25)/0.25+(43-0.25)/0.25+.+(1-0.25)

计算一道数学题,(-370)×(-0.25)+0.25×24.5+(-5.5)×(-0.25)分析:其实这题的关键在于要先把原来的式子变个样子就可以了.我们都知道两个负数相乘的结果是正数,所以在计算时可以把两个负数相乘的式子当中的负号去掉,

梯等式计算0.25*2.1+0.25*8.9-0.25＝0.25x（2.1十8.9一1）＝0.25X10＝2.5=0.25*(2.1+8.9-1)=0.25*10=2.50.25×（2.1+8.9）-0.25

比较0.4^0.250.25^0.25log0.250.5大小0.4^0.25,0.25^0.25均为幂函数,幂指数相同则底数较大者,数值较大故有0.4^0.25>0.25^0.25log0.250.5=ln0.5/ln0.25=ln0.5

67*0.25+2.5*3.75-4.5*0.25简算如题67*0.25+2.5*3.75-4.5*0.25=67×0.25+0.25×37.5-4.5×0.25＝（67+37.5-4.5）×0.25＝100×0.25＝25

用简便方法计算：0.25*39*0.250.25×39＋0.25＝1/4×(39＋1)＝0.25×40＝100.25×39×0.25＝1/4×1/4×39＝1/16×39＝39/16

7.69*1010.25*39+0.25简便运算7.69*101=7.69*(100+1)=7.69*100+7.69*1=769+7.69=776.690.25*39+0.25=0.25*(39+1)=0.25*40=107.69*101

简便计算：0.25×3.2-0.25+1.8×25%原式=0.25×（3.2+1.8-1）=0.25×4=10.25×（3.2-1+1.8）=10.25×3.2-0.25+1.8×0.250.25(3.2-1+1.8)0.25*410.00
