To simplify the expression \((4x^4y^{-4})^3(x^7y^3)^2\) using the properties of integer exponents, follow these steps:
-
Simplify each part separately:
- For \((4x^4y^{-4})^3\):
\[
(4^3)(x^{4 \cdot 3})(y^{-4 \cdot 3}) = 64x^{12}y^{-12}
\]
- For \((x^7y^3)^2\):
\[
(x^{7 \cdot 2})(y^{3 \cdot 2}) = x^{14}y^6
\]
-
Combine the results:
Now, we multiply the two results:
\[
(64x^{12}y^{-12})(x^{14}y^6)
\]
To combine the terms with the same base, we add the exponents:
- For \(x\):
\[
x^{12 + 14} = x^{26}
\]
- For \(y\):
\[
y^{-12 + 6} = y^{-6}
\]
-
Putting it all together:
This gives us:
\[
64x^{26}y^{-6}
\]
-
Rewrite y with a positive exponent:
To express \(y^{-6}\) in a positive exponent, we can write it as:
\[
\frac{64x^{26}}{y^6}
\]
Now, looking at the provided responses, the expression simplifies to:
\[
\frac{64x^{26}}{y^6}
\]
