I totally need urgent help on these exponential equations. I am so confused write now. I know that the bases for each equation has to be the same and that is x is squared you have to factor or use the quadratic formula to find the solution. I also know that the general steps to solve these equations are to make the bases on each side of the equation the same. You have to set the exponents equal to each other. Lastly, you solve for x. I am still confused, I could do the examples in the lesson, but no these practice problems. Help!

1. 9^(2x)=27^(x-1)

2. 5^(n-1)=1/25

3. 25^x=5^(x^2-15)

4. (2^x)(4^(x+5))=4^(2x-1)

5. (sqrt 3)^(2x+4)=9^(x-2)

For the first equation, I think that x=-1. For the second equation, I think that n=1/2. For the other equations, I have no idea what to do.
