Answer:
[tex]4[/tex]
Step-by-step explanation:
(2^2x^2/xy^3)^2
For x=4 and y=2. (given)
now,
[tex]( \frac{2^2x^2}{xy^3} ) {}^{2} \\ \\ ( \frac{ {2}^{2} \times {4}^{2} }{4 \times 2 {}^{3} } ) {}^{2} \\ \\
( \frac{4 \times 16}{4 \times 8 {}^{} } ) {}^{2} \\ \\ ( \frac{64}{32} ) {}^{2} = (2) {}^{2} = 4[/tex]
