log5(x^2+2x-2)=0,2log5(x+2)-log5y+1/2=0求y底数皆为5,log5(x^2+2x-2)=0,2log5(x+2)-log5y+1/2=0求y底数皆为5,log5(x

log5(x^2+2x-2)=0,2log5(x+2)-log5y+1/2=0求y底数皆为5,
log5(x^2+2x-2)=0,2log5(x+2)-log5y+1/2=0求y
底数皆为5,

log5(x^2+2x-2)=0,2log5(x+2)-log5y+1/2=0求y底数皆为5,
log5(x^2+2x-2)=0,即
x^2+2x-2=1
x=1或x=-3（舍去）
2log5(x+2)-log5y+1/2=0,即
log5[3^2√5/y]=0,即
9√5/y=1
y=9√5

y=5^0.5*3^0.2

解方程：log5(2x+1)=log5(x2-2) 求x的值 log4^x=-2/3 log2^(log5^x)=0log4^x=-2/3 log2^(log5^x)=0 分开的 log5 2+log5 3+log5 1/6=? 额,求解指数方程log5（2x²-3x+1) -log5（x-1）+log5（125）=6谢啦,log后的5都是底数! 2log5^10+log5^0.25=? 计算2log5^10+log5^0.25= 2log5 10+log5 0.25=? log5(x^2+2x-2)=0,2log5(x+2)-log5y+1/2=0求y底数皆为5, 已知log5(xˆ2;+2x-2)=0,2log5(x+2)-log5y+1/2=0,求y值 已知log5(x+2x-2)=0,2log5(x+2)-log5y+1/2=0,求y的值 比较log5(x+2)与log5（2x+5)的大小 如果log(2)[log(3)(log5 x)]=0,那么X=?一时转不过弯 1.e^(x+3)=(e^x)+3 求x2.求x最大值log5(x^2)-log5(x+2)=33.简化tan(2cos^-1(x/5)) y=log5(x*x-4x-12)求它的定义域 xx-4x-12>0 (x-6)(x+2)>0 => x>6 或 x 求导 f(x)=log5(2x+1)-3x^2 1.方程(log5 x)²+2log25x-2=0的解集是 2log5(15)-log5(18)+log5(2) 急 对数函数 2log5(15)-log5(18)+log5(7)
