To simplify [tex]\(\left(2^{-5} \times 2^8\right)^2\)[/tex], we will utilize the properties of exponents step by step:

### Step 1: Simplify the expression inside the parentheses
We start by simplifying the expression [tex]\(2^{-5} \times 2^8\)[/tex] which is inside the parentheses.

Using the property of exponents that states [tex]\(a^m \times a^n = a^{m+n}\)[/tex]:

[tex]\[ 2^{-5} \times 2^8 = 2^{-5 + 8} \][/tex]

### Step 2: Combine the exponents
Next, we perform the addition in the exponent:

[tex]\[ -5 + 8 = 3 \][/tex]

So, the expression simplifies to:

[tex]\[ 2^3 \][/tex]

Now, our original problem [tex]\(\left(2^{-5} \times 2^8\right)^2\)[/tex] has been simplified to [tex]\((2^3)^2\)[/tex].

### Step 3: Raise the simplified expression to the power of 2
The next step is to raise [tex]\(2^3\)[/tex] to the power of 2.

Using the property of exponents [tex]\((a^m)^n = a^{m \times n}\)[/tex]:

[tex]\[ (2^3)^2 = 2^{3 \times 2} \][/tex]

### Step 4: Multiply the exponents
Perform the multiplication in the exponent:

[tex]\[ 3 \times 2 = 6 \][/tex]

Thus, [tex]\((2^3)^2\)[/tex] simplifies to:

[tex]\[ 2^6 \][/tex]

So, the simplified form of [tex]\(\left(2^{-5} \times 2^8\right)^2\)[/tex] is [tex]\(\boxed{2^6}\)[/tex].
