  • B: IF exponent > 1
    SET result TO result * number 
       SET exponent TO exponent – 1 
    END IF 
    Return result 
  • C: IF exponent > 1
    SET result TO result * number 
       SET exponent TO exponent + 1 
    END IF 
    Return result 
  • D: WHILE exponent > 1
       SET result TO result * number 
       SET exponent TO exponent + 1 
    LOOP 
    Return result
