Let's solve the expression $2^{3^{3-5^{2+1}}}$.

Step 1: Simplify the exponent inside the innermost expression

Start with the expression $5^{2+1}$:

$5^{2+1} = 5^3 = 125$

Step 2: Substitute back into the next exponent

Now, substitute $125$ into the expression:

$3^{3 - 125}$

Step 3: Simplify the exponent

$3 - 125 = -122$

So the expression becomes:

$2^{3^{-122}}$

Step 4: Simplify the entire expression

Now you have $2^{3^{-122}}$.

Since $3^{-122}$ is a very small fraction (close to zero), $2^{3^{-122}}$ is slightly larger than 1, but extremely close to 1.

Final Answer:

$2^{3^{3-125}} = 2^{3^{-122}} \approx 1$
