3.6+3.2+3.6+4+3.6=3x3.6+3.2+4=3x3.6+2x3.6=5x3.6=18
46.24-8.76-1.34=46.24-(8.76+1.34)=46.24-10.1=36.14
设酸奶为每袋X元,牛奶为每袋Y元4X+6(X-0.8)=21.24X+6X-4.8=21.210X=21.2+4.8X=26÷10X=2.6Y=X-0.8=2.6-0.8=1.8
6.4×0.25+3.6÷4=6.4×1/4+3.6÷4=6.4÷4+3.6÷4=（6.4+3.6）÷4=10÷4=2.5
3.6-3.6*4分之3+8分之7*5除以8分之7*5＝3.6*（1-3/4）+1＝0.9+1＝1.9
请问log(2)3.6是如何等于log(4)3.6的平方log(4)3.6²=2log(4)3.6=2log(2²)3.6=(2×1/2)log(2)3.6=log(2)3.6;如
4.8:4=x:3.64x=4.8*3.6x=4.8*0.9x=4.324：4.8=x:3.64.8x=4*3.6x=3
2/9x3.6=2/9x9x0.4=2x0.4=0.81/4x3.6=1/4x4x0.9=1x0.9=0.9
简便算法么?58.76-（8.76-15）=58+0.76-（8+0.76-15)=58+0.76-8-0.76+15=58-8+15+0.76-0.76=65
(1.6乘4)乘0.25加3.6除4=1.6乘4乘0.25加0.9=1.6乘1加0.9=1.6+0.9=2.5
你好21.6－0.8×4÷0.8×4=21.6－4×4=21.6－16=5.63.6×3.7＋3.6＋5.3×3.6=3.6×（3.7+1+5.3）=3.6×10=36很高兴为您解答,祝你学习进步!有
6.4*0.25+3.6/4=6.4/4+3.6/4=(6.4+3.6)/4=10/4=2.5
4:3=3.6:x所以4x=3×3.6=10.8x=2.7如果还没学方程那就直接算3.6÷4×3=2.7所以4:3=3.6:2.7
25×4=10058-58=0480÷60=88.76-4.27=4.498×9+8=80360÷36=101000×0.013=133-1.4=1.645×20=900125×7×8=70000.3
3.6*0.75+3.6/4=3.6*0.75+3.6*0.25=3.6*（0.75+0.25）=3.6*1=3.6
4x-3.6=5分之4x+64x-0.8x=6+3.63.2x=9.6x=3
（21.2×6.9+21.2×3+6.9×3）×2=461.16
4.8/(x/4.5)-3.6/(x/4.5)=0.21.2/(x/4.5)=0.2x/4.5=6x=6×4.5x=27
第一题：1/4×（48.5÷5/18－3.6+6.15×3.6） =1/4×((48×2+1)/10/18+(5×20+3)/20×(3×5+3)/5) =1/4×(96/10/18+1/10/1
