4.25^x=1000,0.00425^y=1000,求x分之1-y分之一的值
4.25^x=1000,0.00425^y=1000,求x分之1-y分之一的值
4.25^x=1000,0.00425^y=1000,求x分之1-y分之一的值
4.25^x=1000 ,两边 1/x 次方,得 4.25=1000^(1/x) ,
同理在 0.00425^y=1000 的两边 1/y 次方,得 0.00425=1000^(1/y) ,
两式相除得 1000^(1/x-1/y)=4.25/0.00425=1000=1000^1 ,
所以 1/x-1/y=1 .
已知:4.25^x=1000,0.00425^y=1000,求1/x-1/y
4.25^x=1000,0.00425^y=1000,求x分之1-y分之一的值
x+1000-x=1000,x=?
X+0.3X=1000 求X?
X=28.1%*(1000+X)求X
x^3+x^2+3x=1000 x=?
X/(X+1000)=5%
x+(x*0.17)=1000
(X+X)+(X-X)+(X*X)+(X/X)=100
求x 的值.x +3.5x =9.9;4.25x -x =4.55;10x -2.7x =58.4;6.8x +3.2x =100
解方程1000*X^5-59(X^4+X^3+X^2+X)=1000
设f(x)=x(x-1)(x-2).(x-1000) 则f'(0)=?RT
Fx=x(x-1)(x-2)(x-3)…(x-1000) 求 F'(0)
x*x*x*x*x=80000?
y=x+2000 3x-y=1000x
X²+(1000--X)²=4X²,
2500+x=1000+2x x等于多少
10^(x^2)=1000/(10^x)^2,求x
