32.14+64.28x0.5378x0.25+0.5378x64.28x0.75-8x64.28x0.125x0.5378

Answer 1

32.14+64.28x0.5378x0.25+0.5378x64.28x0.75-8x64.28x0.125x0.5378
=32.14+0.5378*64.28*（0.25+0.75）-64.28*（8*0.125）*0.5378
=32.14+0.5378*64.28*1-0.5378*64.28*1
=32.14

Answer 2

32.14+64.28x0.5378x0.25+0.5378x64.28x0.75-8x64.28x0.125x0.5378

Answer 3

设32.14=x 原式=x+2x*0.5378*0.25+0.5378*2x*0.75-8*2x*0.125*0.5378=x+0.5378*2x*(0.25+0.75-8*0.125)
=x+0.5378*0=x=32.14

Answer 4

32.14，用乘法分配律

Answer 5

设32.14=x 原式=x+2x*0.5378*0.25+0.5378*2x*0.75-8*2x*0.125*0.5378=x+0.5378*2x*(0.25+0.75-8*0.125)
=x+0.5378*0=x=32.14
