For (1) do you mean
Then,
Let
and solve to find
For (2) take the log of both sides:
Now use the quadratic equation to find your solutions. Where,
For (3) again take the log of both sides.
hi i need help on solving these questions with all the log rules i'm confusing myself..
1). 7^(x-2) = 1/2^(x-2)
2). 10^(x^2+2x-8) = 1
3). (1/4)^(x+2) * 32^(x-1) = 64^(x-2)
i know i have to solve for x but i keep getting the wrong answers when i plug it into my graph and find the intersections for the answer.
thanks!
