Question 91336
x = log7(1/49)
==============
Think of a logarithm in terms of what it means in exponent form.
The "7" is the base, the "1/49" is the answer, and the logarithm is the exponent. In other words, you problem can be re-written as:
{{{7^x=1/49}}}
When written in this form, you can easily see that 
{{{highlight(x=-2)}}}
That is your answer.
Good luck,
