The best way to solve equations with fractions is to get a common denominator. So, 3/4 will become 6/8 and 1/8 will stay. Now we can solve: when dividing fractions with common denominators, it is easy to just find how many times the smaller one fits into the larger one. So, 1/8 goes into 6/8 six times. In conclusion, the answer is 6 rose gardens.

Hint: substitute 2^x by say 't': t = 2^x, then you'll have an inequality with a second order polynomial (2/t-4*t<7--> ...). In the end something like t^2 + a*t+b > 0, for some values of a and b, find the roots and get the intervals where it is satisfied.
