However, Leonhard Euler [2] believed it originated from the letter "r", the first letter of the Latin word "radix" (meaning "root"), referring to the same mathematical operation. The symbol was first seen in print without the vinculum (the horizontal "bar" over the numbers inside the radical symbol) in the year 1525 in Die Coss by Christoff ...
"A base is a natural number B whose powers (B multiplied by itself some number of times) are specially designated within a numerical system."
