简便运算0.37*0.37+2*0.63*0.37+0.63*0.63
简便运算0.37*0.37+2*0.63*0.37+0.63*0.63
简便运算0.37*0.37+2*0.63*0.37+0.63*0.63
0.37*0.37+2*0.63*0.37+0.63*0.63
=(0.37*0.37+0.63*0.37)+(0.63*0.37+0.63*0.63)
=0.37*(0.37+0.63)+0.63*(0.37+0.63)
=0.37*1+0.63*1
=1
0.37*0.37+2*0.63*0.37+0.63*0.63=0.37*0.37+0.63*0.37+0.63*0.37+0.63*0.63
=0.37*(0.37+0.63)+0.63*(0.37+0.63)=0.37+0.63=1
=(0.37+0.63)²
=1
＝﹙0.37＋0.63﹚²＝1
