| Unfortunately, while multiplication is easy in the exponent representation, addition becomes very difficult, and therefore this representation often cannot be used in practice. Nevertheless, even knowing that such a representation exists gives valuable insight into the multiplicative structure of finite fields, which can be used to discover their properties, as we shall see in the next lesson. | Unfortunately, while multiplication is easy in the exponent representation, addition becomes very difficult, and therefore this representation often cannot be used in practice.
