Question 167694: Solve for b:
t+=+9%5Esquare+root+of+b
Multiple choice answers are:
A. b+=+t%5E2%2F81
B. b+=+t%2F81
C. b+=+t%2F9
D. none of the above
NOTE: none of the above is not the correct answer because that's what I put and I got it incorrect.

You can put this solution on YOUR website!
solve for b:
t = 9^square root of b
------------
Take the log of both sides to get:
log(t) = (sqrt(b))log(9)
sqrt(b) = [log(t)/[log(9)]
b = [log(t)/[log(9)]^2
======================
A. b+=+t%5E2%2F81
B. b+=+t%2F81
C. b+=+t%2F9
D. none of the above
======================
The answer is "none of the above" for the problem you have posted.
If the answer is not "none of the above" the problem is not the
one you posted.
