To solve the equation E + sqrt(aE) = b for E, first rewrite it as sqrt(aE) = b - E. Next, square both sides to eliminate the square root, resulting in aE = (b - E)². This leads to a quadratic equation in E, which can be rearranged and solved using standard methods for quadratic equations. The constants 'a' and 'b' will determine the specific solutions for E. Understanding this process is crucial for tackling similar exponential equations with square roots.

Homework Statement


How do you solve this probem for E:

E + sqrt(aE) = b

where 'a' and 'b' are constants.

I don't recall how to handle the exponents where you have E + aE^1/2 = b and solve for E.

Rewrite it as sqrt(aE)=b-E. Now square both sides. It's a quadratic equation in E.
 
Thank you.
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
