## Description
|
|
<section id='description'>
|
|
|
|
A googol (10<sup>100</sup>) is a massive number: one followed by one-hundred zeros; 100<sup>100</sup> is almost unimaginably large: one followed by two-hundred zeros. Despite their size, the sum of the digits in each number is only 1.
|
|
|
|
Considering natural numbers of the form, <var>a<sup>b</sup></var>, where <var>a</var>, <var>b</var> < 100, what is the maximum digital sum?
