Answer:
C. [tex]x^2y[/tex]
Step-by-step explanation:
Given the expression [tex](x^4y^2)^{\frac{1}{2} }\\[/tex]
Using the law of indices;
[tex](a^m)^n = a^{mn}[/tex]
[tex](x^4y^2)^{\frac{1}{2} }\\\\= (x^4)^{\frac{1}{2}} (y^2)^{\frac{1}{2} }\\= x^{4*1/2}y^{2*1/2}\\= x^{2}y[/tex]
Hence the correct answer is [tex]x^2y[/tex]
