Beyond the Answer
To simplify the expression \( \left(4 x^{2} y^{-2}\right)^{2} \), let's apply the power of a product rule. Each factor inside the parentheses is raised to the power of 2. That means we'll raise 4, \( x^{2} \), and \( y^{-2} \) individually: 1. \( 4^{2} = 16 \) 2. \( (x^{2})^{2} = x^{4} \) (by multiplying the exponents) 3. \( (y^{-2})^{2} = y^{-4} \) Now, putting it all together: \( (4 x^{2} y^{-2})^{2} = 16 x^{4} y^{-4} \) This can be expressed with positive exponents in the denominator, giving: \( 16 x^{4} \cdot \frac{1}{y^{4}} = \frac{16 x^{4}}{y^{4}} \) So the final simplified result is: \(\frac{16 x^{4}}{y^{4}}\)
