(1) 100^3000=(100^2500)(25^500)(4^500)
(2) 500^2500=(100^2500)(25^500)(5^1500)
so, (2)>(1)
(3) 2000^2000=(2000^1500)(2000^500)
(4) 4000^1500=(2000^1500)(8^500)
so, (3)>(4)

比較 (2) 和 (3)
(2) 500^2500=(5^2500)(2^1500)(10^3500)(5^1500)
(3) 2000^2000=(5^2500)(2^1500)(10^3500)(4^1500)
so, (2)>(3)
so 500^2500 is the largest number.

應該係100的3000次方.

I THINK

4000*1500
you should edit the question....
not"which one is the LARGE" is "which one is the LARGEST"
