the number you are talking about is much, much larger...

 

Usually, when dealing with exponents, you'd like add parenthesis. But, the convention in absence would be a^b^c^d = a^(b^(c^d))

so,

10^56 has 56 zeroes;  (already a number far beyond our imagination)

10^(10^56) has 10^56 zeroes (a number which visually we couldn't ever be able to imagine seeing written down)

 

 

10^(10^(10^56)) has 10^(10^56) zeroes. 

 

Those are numbers which our brain isn't in any way adequate for to imagine, or even to try to represent in any more comprehensible form than just 10^(10^(10^56))
