if p = 125 × 243 × 16 / 405 , how many digits are in p ?
p = 125 * 243 * 16 / 405 p = 5 ^ 3 * 3 * 9 ^ 2 * 4 ^ 2 / ( 5 * 9 ^ 2 ) p = 5 ^ 2 * 3 * 4 ^ 2 p = 20 ^ 2 * 3 = 1200 answer d
divide(multiply(multiply(divide(243, divide(405, add(const_4, const_1))), 16), divide(125, add(const_4, const_1))), multiply(const_100, const_3))
