1/3+(-1/5)-1+3/2
=1/3-1/5-1+3/2
=(1/3+3/2)-(1/5+1)
=11/6-6/5
=55/30-36/30
=19/30
0.5+(-1/4)-(-2.75)+1/2
=0.5-1/4+2.75+1/2
=0.5-0.25+2.75+0.5
=3.5
(2/3)+(-1/6)-(1/4)-1/2
=2/3-1/6-1/4-1/2
=(2/3-1/6-1/2)-1/4
=0-1/4
=-1/4
1+1/2^0.5+1/3^0.5+...+1/n^0.5
1+2+3+5+8+9+0.5+0.5=
-1-{1-[2-0.5×(3/1)]}
在五个0.5之间填上符号或括号,使等式成立.(1)0.5 0.5 0.5 0.5 0.5=0(2)0.5 0.5 0.5 0.5 0.5=1(3)0.5 0.5 0.5 0.5 0.5=2(4)0.5 0.5 0.5 0.5 0.5=3(5)0.5 0.5 0.5 0.5 0.5=4
1/5:2/3 1:5/6 3/8:2 3:0.5 求比值
2-[1-(2分之1×3分之2-1)]×(-0.75)次方+(-0.5)3次方×5次方
计算:(-13/2)×2/3-0.5×2/7+1/3×(-13/2)-5/7×0.5简便、、
加上适当的运算符号和括号,使等式左右两边相等.(1)0.5 0.5 0.5 0.5 0.5=0(2)0.5 0.5 0.5 0.5 0.5=0.5(3)0.5 0.5 0.5 0.5 0.5=1(4)0.5 0.5 0.5 0.5 0.5=1.5(5)0.5 0.5 0.5 0.5 0.5=2.5
化简log2(1+2^0.5+3^0.5)+ log2(1+2^0.5-3^0.5)
2-3/1等于多少 3-9/5 2/1+0.5 7又9/4-5
计算-1又3/5-1/2+3/4-2/5+0.5-7/8
-1-(1-0.5)×1/3×[2-(-3)2]【计算过程】-1-(1-0.5)×1/3×[2-(-3)²]
1/2×( )=3/5×( )=0.5×( )=
计算:1) 2-[1-(1/2*2/3-1)]*(-0.75)2次方+(-0.5)3次方*5的2次方
-(-3)²×(-1)-8×(-1/2)³×l-2-3l-1⁴-(1-0.5)×1/3×[2-(-3)²][(-1/6)-(-5/12)+2/12]×(-60)
(1/2)^-3-2^100*0.5^100*(-1)^2005/(-1)^-5
-0.5+(-3分之2)-(绝对值:-5分之4)-(-2分之1)-(+3分之1)
-0.5+(-2/3)-I-4/5I-(1/2)-(+1/3) 怎么算
