Question 413463: Solve for R
M= 14p/r^2
I'm thinking sqrt%2814p%2Fm%29 or sqrt%2814p%2Fm%29+%5E2 But I'm not sure if either of those are even close. (the 2nd option should have the whole thing squared not just the p, not sure why it keeps coming up wrong.
I appreciate the help! Thanks!!

You can put this solution on YOUR website!
M+=+%2814p%29%2Fr%5E2
M%2Ar%5E2+=+14p
r%5E2+=+%2814p%29%2FM
r+=+sqrt%2814p%2FM%29
and, also
r+=+-sqrt%2814p%2FM%29
Both positive and negative square roots are valid
