1 answer

To simplify the expression \( 2^4 \cdot 11^{-5} \cdot 11^7 \), we can start by simplifying the powers of \( 11 \).

Recall that the property of exponents states that when multiplying with the same base, you add the exponents:

\[ 11^{-5} \cdot 11^7 = 11^{-5 + 7} = 11^2 \]

Now, we can rewrite the entire expression:

\[ 2^4 \cdot 11^{-5} \cdot 11^7 = 2^4 \cdot 11^2 \]

Next, we calculate the values of \( 2^4 \) and \( 11^2 \):

\[ 2^4 = 16 \] \[ 11^2 = 121 \]

Now, substituting these values back into the expression:

\[ 2^4 \cdot 11^2 = 16 \cdot 121 \]

Next, we multiply \( 16 \) by \( 121 \):

\[ 16 \cdot 121 = 1936 \]

Thus, the final answer is:

\[ \boxed{1936} \]
