Just remove the top 2

Algebra Level 2

2 2 = 2 , 2 2 2 = 2 2 \large \sqrt{2^2} = 2, \qquad \sqrt{2^{2^2}} = 2^2

The above two equalities are both true.

Continuing with the same pattern, can we also claim that 2 2 2 2 = 2 2 2 ? \large \sqrt{2^{2^{2^2}}} = {2^{2^2}}?

No Yes

2 2 = 2 2 2 = 2 \sqrt {2^2}=2^{\frac {2}{2}}=2

2 2 2 = 2 2 2 2 = 2 2 \sqrt {2^{2^2}}=2^{\frac {2^2}{2}}=2^2

2 2 2 2 = 2 2 4 2 = 2 8 2 2 2 \sqrt {2^{2^{2^2}}}=2^{\frac {2^4}{2}}=2^8≠2^{2^2}
