What is (1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+0+1+1+1+1+1+1+1+1+1+1+1+1)^100*0*9*1*7*3+1

The way you typed it:

(1+1+...+1)^100 * 0 * 1 * ... * 7 * 3 + 1

(1+1+...+1)^100 is some big number, then multiplied by 0 gives 0
so (1+1+...+1)^100 * 0 * 1 * ... * 7 * 3 = 0
then 1 is added, so the result is 1

if you meant:
(1+1+...+1)^(100 * 0 * 1 * ... * 7 * 3) + 1
the exponent is zero, so
you have "some positive number" raised to zero, so that part is 1,
then another 1 added gives you a final answer of 2

See how some silly brackets change the whole mess ?
