Michael and Christopher were supposed to add up the terms of the geometric sequence 1,3,9,…,3^20
and then find the remainder when divided by 40.

Michael did the question correctly and got the answer M, but Christopher took the remainders of each term separately and then added all these remainders up to get the incorrect answer C. What is C−M?

Water is known as hypotonic, ie. very dilute and contains more water than the egg. If instead you place the vinegar soaked egg in corn syrup you will see the opposite. There is a much higher water concentration in the egg than in the syrup so water will pass in the opposite direction.

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5
