what is the square root of one dollar?

The square root of one is one, but the square root of one dollar is not one dollar.

To see that it cannot be one dollar, try the following

1 dollar = 100 cents

therefore by square rooting

1 dollar = 10 cents

oops!

What we forgot to do was square root the units, so we ought to say that the square root of a dollar is, say, one 'root-dollar'!

Don't worry too much about what the 'root-dollar' is, it is just the unit that squares to a dollar.

Therefore

1 root-dollar = 10 root-cents

is true!
