Question

Can you name the biggest number that can be written with four 1s?​

Answer 1

Step-by-step explanation:

People often think of the number 1111 as the biggest number that can be written with four 1s. But there is the number many, many times greater than this number, namely

${11}^{11}$

${11}^{11} = 285311670611$

As you can see

${11}^{11}$

is almost 250 million times greater than 1111.

Answer 2

Yes, (11!)^11!

People may think that 11¹¹ is the biggest possible number which can be formed with only four 1s.

However, 11! ⋙ 11.

So, (11!)^11! ≈ ∞ which is the greatest possible number.
