Using properties of exponents,
\((x^3y^2/2x^4)^(-2) \:is\: 4x^2y^4\)

How did we get the value?

Let's simplify the expression using the properties of exponents:


\((x^3y^2/2x^4)^(-2)\)

First, apply the reciprocal property of exponents
(a^(-n) = 1/a^n):


\((1)/((x^3y^2/2x^4)^(2))\)

Apply the power of a quotient property of exponents
\(((a)/(b))^n = (a^n)/(b^n)\):


\((1)/(((x^3y^2)/(2x^4))^2)\)

Square the numerator and denominator:


\((1)/((x^6y^4)/(4x^8))\)

When you divide by a fraction, it's equivalent to multiplying by its reciprocal:


\((1)/((x^6y^4)/(4x^8))\) is the same as
\((1)/(1) * (4x^8)/(x^6y^4)\)

Simplify further:


\((4x^8)/(x^6y^4)\)

Now, subtract the exponents in the numerator:


\(4x^(8-6)y^4\)


\(4x^2y^4\)

So,
\((x^3y^2/2x^4)^(-2) = 4x^2y^4\)
