WebFirst write the exponent 25 in binary: 11001. Remove the first binary digit leaving 1001 and then replace each remaining '1' with the pair of letters 'sx' and each '0' with the letter 's' to get: sx s s sx. Now interpret 's' to mean square, and 'x' to mean multiply by x, so we have: square, multiply by x, square, square, square, multiply by x.
