Question 31403: I see this question has already been asked, but I think it was submitted incorrectly. Solve the equation. Give an exact solution.
4^(x+6) = 7
Please help with this.
Here is another one that I am having trouble with.
Write the equation in its equivalent logarithmic form.
10^2 = y
I think the answer is logy = 2
but I am not sure why or how to get there.
thanks in advance for all your help!!

You can put this solution on YOUR website!
1) Take the log of both sides to get:
(x+6)log6 = log7
x= (log7)/(log6)-6
x= 0.9540-6
x= -5.046
2) correct; you see that the exponent is "2".
So you write log = 2
Then you aswer the question; exponent that produces what?
Answer: y
So you write it as log y = 2
meaning "The exponent that produces y is 2".
