(-125 5/7)/(-5)-2.5+5/8*(-0.25)等于几
(-125 5/7)/(-5)-2.5+5/8*(-0.25)等于几
(log(2)125+log(2)25+log(8)5)*(log(125)2+log(25)4+log(5)8)
(-0.125)^8x2^25=
[log2 (125) +log4(25)+log8(5)][log125(8)+log25(4)+log5(2)
(125+0.125+1.25)*8
求:(log2 125+log4 25+log8 5)(log125 8+log25 4+log5 2);
简便计算4.8/0.125+5.2*8 3.75*0.2+6.25/5 24*11/23 120/1.25/8 12*1
