Hi everyone!

## Tally

The current tally is 6.

## The Question of the Day

How many times can you subtract 5 from 25? Think carefully.

## Previous Solution

Note that (3 - sqrt 5)(3 + sqrt 5)= 9-5 = 4. Thus x times (3+sqrt 5 )/2 = 1, so x+1/x = 3. Squaring both sides, we obtain the equation x^2+2+x^-2= 9. So, x^2 + x^-2 = 7. Squaring both sides again, we find that x^4+2+x^-4=49, so x^4+x^-4=47. Squaring both sids one last time, we find that x^8+2+x^-8 = 2209, so x^8+1/x^8 = 2207.

It was not an irrational number! YAY!
