I just did it and there are a few problems that are stumping me. It's simple stuff it's just been a while since I've done it. Can somebody please explain how to get the answers to the following questions?

x^2-14x>15 is equivalent to ?

7^x = 3, x = ?

t = e^(x+2), x = ?

((x^2-4)/(5x))*(30/(3x-6)) = ?

8^(2/3)*16^(1/4) = ?

log base10 s = 4, s = ?

Thanks!!
