WebWhen an exponent is 1, the base remains the same. a 1 = a . When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Shown below is an example of an argument for a 0 =1 using one of the previously … WebModular exponentiation Google Classroom Finally, let's explore the exponentiation property: A^B mod C = ( (A mod C)^B ) mod C Often we want to calculate A^B mod C for large values of B. Unfortunately, A^B becomes very large for even modest sized values for B. For example: 2^90 = 1237940039285380274899124224

In this method, you should first compute the binary form of e. Let ℓ be the number of bits in e, and let e i denote the i -th bit of e, so that e = ∑ i = 0 ℓ e i ⋅ 2 i.
