Start by reviewing your knowledge of natural logarithms. If we take the ln of both sides we get e^z=ln(1). Do the same thing again and wheel about the ln(ln(1)). There's going to be complex solutions, Wolfram Alpah gets them but let me know if you figure out how to do it?
Answer:

The answer is $45.50
Step-by-step explanation:
First, divide 26.00 by four. This will give you 6.5, so now you know that each ticket individually costs $6.5 or $6.50.
next, multiple 6.50 by 7.
this will give you 45.5 or $45.50.
double check your answer by dividing 45.50 by 7.
your answer should be 6.5 on a calculator.
that's all! hope this helped.
