计算下列各式.(1)0.125^6乘(-8)^7+(1/2-6)^0;(2)x^10•x^5+(x^3)^5+4(x^5
解方程 (1)x+ 2 3 = 4 5 (2)x- 7 8 = 1 4 (3) 1 6 -2x=0.125.
1/2x+3=1/3x+2 0.5x-0.7=6.5+0/2x 1-7/3x=2/3x+19 0.4x-1/4=8-1/
[x/0.2−1=1.7−2x0.3+0.5+2x0.6].
解方程① 1 6 (3x-6)= 2 5 x-3 ② x 0.5 - 3x-1 0.7 =5 .
5x+125小于等于0 6-2x大于0 —x+1大于7x-3 2(1-3x)大于3x+20 2分之2x-1小于2分之x
5(2-x)=-(2x-7) 0.5x-2=0.8(2x-1.5) 2(x+0.5)-3(x-0.4)=5.6
(-0.125)^12x(-1又2/3)^7x(-8)^13x(-3/5)^9
5/12x-x/4=1/3 0.5x-0.7=6.5-1.3x 3(x-7)+5(x-4)=15 (y-1)/2=2-(
