A. No restrictions
B. [tex]x \neq 0, y \neq 0[/tex]
C. [tex]x \neq 0[/tex]
D. [tex]y \neq 0[/tex]



Answer :

To determine the restricted values for the given expression \(\frac{3xy^2}{4y} \div \frac{2x^2}{3y}\), we need to identify the values of \(x\) and \(y\) that would make any part of the expression undefined.

Let's start by simplifying the expression step-by-step.

1. The given expression is:
[tex]\[ \frac{3xy^2}{4y} \div \frac{2x^2}{3y} \][/tex]

2. The division of fractions can be transformed into multiplication by the reciprocal of the second fraction:
[tex]\[ \frac{3xy^2}{4y} \times \frac{3y}{2x^2} \][/tex]

3. Now, simplify each part of the multiplication. Simplify \(\frac{3xy^2}{4y}\):
[tex]\[ \frac{3xy^2}{4y} = \frac{3x \cancel{y^2}}{4 \cancel{y}} = \frac{3xy}{4} \][/tex]

4. Next, simplify \(\frac{3y}{2x^2}\):
[tex]\[ \frac{3y}{2x^2} \text{ cannot be simplified further.} \][/tex]

5. Multiply the simplified fractions:
[tex]\[ \frac{3xy}{4} \times \frac{3y}{2x^2} = \frac{(3xy) \cdot (3y)}{4 \cdot 2x^2} \][/tex]
[tex]\[ = \frac{9xy^2}{8x^2} \][/tex]

6. Simplify the resulting fraction:
[tex]\[ \frac{9xy^2}{8x^2} = \frac{9 \cancel{xy^2}}{8 \cancel{x^2}} = \frac{9y^2}{8x} \][/tex]

In the simplified expression \(\frac{9y^2}{8x}\), values of \(x\) and \(y\) that make the denominator zero need to be excluded, as division by zero is undefined.

- For the simplified form \(\frac{9y^2}{8x}\), the denominator is \(8x\). For this to be defined, \(x\) should not be zero.

Additionally, from our initial steps:

- In the original fractions \(\frac{3xy^2}{4y}\) and \(\frac{2x^2}{3y}\), \(y\) should not be zero to avoid division by zero in both fractions.

Therefore, the restricted values are that both \(x\) and \(y\) should not be zero.

The correct answer is:
[tex]\[ \boxed{x \neq 0, y \neq 0} \][/tex]
