To construct this number you first start with ten you then multiply it by ten to get 100 after that you multiply the 100 you got previously to get ten thousand you then multiply the ten thousand by ten thousand to get 100 million you multiply the 100 million by 100million to 10 quadrillion you then multiply ten quadrillion by quadrillion to get 100 nonillion or ten to the 32 you then square that number to 10^64 you square that number to get 10^128 you square it again to get 10^256 you square it again to get 10^512 you square it again to get 10^1024 you square it again to get 10^2048. You then move on from squaring and start raising it to the power of 4 and no this isn't a typo.After you raise the number you got previously to the power of 4 you get10^8192 you then raise that number to the power of 4 to get 10^32768 you then raise that number to the power of 4 to get 10^65536 you then raise this number to the power of 4 to get 10^262144 you raise that to power of 4 to get10^1048576.Now once you've got that number you don't raise it to the power of 8 you raise it to power of 16 to get 10^16777216 you then raise that number to the power of 16 to get 10^268435456 you then raise that to the power of 16 to get 10^42944967296 you then raise this number not to the power of 32 or even the power of 64 not even the power of 128 no you raise it to the power of 256. so after you do that you get 10^1099511627776 you then raise that to power of 16 to get 10^2184749767107x10^14 so just over ten to 200 trillion. You then raise that number to power of 65536 to get 10^1.844674407371x10^17 to then raise that number to the power of 2^10^10^64 you raise that number to power of 2^10^10^10^10^10^10^10^10^10^10... where the number of ^10's is 2^10^10^64. you then take that number and exponentiate it 2^10^10^64 times but this isn't even the start of this number you then repeat this process process 2^10^10^64 times. But you aren't finnished yet you then have to raise it to the power of 2^10^10^10^10^10^10^10^10^10^10^10....^64 where the number of ^10's is 2^10^10^10^10^10^10^10...10^64 where the number of 10^'s is 2^10^10^10^10^10^10^64 you then this repeat 10^10^10^10^64 times then repeat again another 10^10^10^10^64 times. You then repeat the process 10^10^10^10^10^10^64
In total you have to repeat it 10^10^10^10^10^10^10^10^10^10^10^10^10^10^10^10^10^64 times.
Once you've done that your finnished.
