Math Problem Statement

Bentuk pangkat positif dari \left( \frac{3x^{-2} y^3}{2x^{-3} y^2} \right)^2 adalah ....

Solution

The problem asks for the positive exponent form of the expression:

(3x2y32x3y2)2\left(\frac{3x^{-2}y^3}{2x^{-3}y^2}\right)^2

Let's simplify this step-by-step.

Step 1: Simplify inside the parentheses

We start by simplifying the fraction inside the parentheses:

3x2y32x3y2\frac{3x^{-2}y^3}{2x^{-3}y^2}

For the xx terms: x2x3=x2(3)=x1\frac{x^{-2}}{x^{-3}} = x^{-2 - (-3)} = x^{1}

For the yy terms: y3y2=y32=y1\frac{y^3}{y^2} = y^{3 - 2} = y^1

So, the fraction simplifies to: 3x1y12\frac{3x^1y^1}{2}

Or more simply: 3xy2\frac{3xy}{2}

Step 2: Apply the square

Now we square the entire expression: (3xy2)2=(3xy)222=9x2y24\left(\frac{3xy}{2}\right)^2 = \frac{(3xy)^2}{2^2} = \frac{9x^2y^2}{4}

Final Expression:

9x2y24\frac{9x^2y^2}{4}

Thus, the positive exponent form of the expression is 9x2y24\frac{9x^2y^2}{4}.

Answer:

The correct option is d. 9x2y24\frac{9x^2y^2}{4}.
