We can solve the expression \( 8\log27 \times 3\log4 + 2\log16 \) by using properties of logarithms and simplifying step by step.

### Step 1: Simplify the logarithms using the exponent rule
The logarithmic property \( a\log b = \log b^a \) allows us to move the coefficients inside the logarithm as exponents. Let's apply this property:

\[
8\log 27 = \log 27^8
\]
\[
3\log 4 = \log 4^3
\]
\[
2\log 16 = \log 16^2
\]

Now we have:

\[
\log 27^8 \times \log 4^3 + \log 16^2
\]

### Step 2: Simplify the expressions
Now, compute the powers:

\[
27^8 = (3^3)^8 = 3^{24}
\]
\[
4^3 = (2^2)^3 = 2^6
\]
\[
16^2 = (2^4)^2 = 2^8
\]

Substituting these into the expression:

\[
\log 3^{24} \times \log 2^6 + \log 2^8
\]

### Step 3: Use the logarithmic power rule
Using the logarithmic rule \( \log a^b = b\log a \), we simplify further:

\[
24\log 3 \times 6\log 2 + 8\log 2
\]

### Step 4: Multiply the terms
Now, calculate the multiplication:

\[
(24\log 3) \times (6\log 2) = 144 (\log 3 \times \log 2)
\]
So, the expression becomes:

\[
144 (\log 3 \times \log 2) + 8\log 2
\]

This is the simplified form.
