Hello, strangepath!
That's quite a list, but I see that they require a variety of tecnniques.
I'll solve a few of them.
Take logs: .
. . . . . . . . .
This one is deceptively simple.
Factor: .
Take logs: .
We are expected to know that: .
The equation becomes: .
. . . We must discard x = -2.
Multiply by
Factor: .
And we have two equations to solve:
