解方程2log(x)8-3log(8)X=1.(提示:设log(x)8=t,用换元法)
对数计算1.{log(4)(3)+ log(8) (3)} X {log(3)(2)+log(9)(2)}2.{log(
log(x+5)=log(x)+log(2) log(8)+log(x)=log(24) 2log(x)=log(2x)
解方程 log2(x+14)+log(x+2)=log(x+6)+3
log 8下标 (X-6)+ log 8小标 (x+6)=2 求X
已知log(2)[log(3)(log(4) x)] = log(3) [log(4) (log(2) y)]=0,求x
log 8 16=x 怎么解
log(0.5x)(2)-log(0.5x^3)(x^2)=log(0.5x^3)(4)
log₂log₃log₄ X=log₃log₄logS
1/log(2)x+1/log(3)x+1/log(4)x=1,x=?
设函数f(2x)=log(8x平方+7),则f(1)=?
设f(x)=log
一道高一数学题:解方程:log(0.5x)(2)-log(0.5x^3)(X^2)=log(0.5x^3)(4) 求大神
