问3个数学题 1.Find a formula for the inverse of the function.f(x) = e的x次方的9次方 f -1(x)=（）
2.Find a formula for the inverse of the function.
y = 9x的3次方 + 8
y=?
3.Solve each equation for x.(Enter an exact answer.)
(a) ln(ln(x)) = 1
x=()?
(b) e的ax次方 = Ce的bx次方,where a 不等于 b
x = （）?

1.f(x) = e^x 的反函数为(lnx)^(1/9)
2.y = 9x^3+8 的反函数为y = [(x-8)/9]^(1/3)
3.(a)ln(ln(x)) = 1
lnx = e
x = e^e
(b) e^(ax) = Ce^(bx)
ax = bx + lnC
(a-b)x = lnC
x = (lnC)/(a-b)
