I got number 1 correct, I'm assuming you had a typo in a question. And I'm assuming the giant E in number 2 is supposed to represent sigma in which case, it's a summation of all of the I terms from 1 to 100. In the case, I = 100, the number is 100^(7.6 x 10^12). That's a pretty $%#^%# large number.
