Math Problem Statement

Simplify the expression: ((8x^(-2)y^0) / (4x^(-3)y^(-3)))^3

Solution

Let's break down the expression from the image step by step:

The given expression is:

(8x2y04x3y3)3\left( \frac{8x^{-2}y^0}{4x^{-3}y^{-3}} \right)^3

Step 1: Simplify the fraction inside the parentheses

First, simplify the coefficients, 88 and 44: 84=2\frac{8}{4} = 2

Now, simplify the exponents of xx and yy:

For xx, apply the rule xaxb=xab\frac{x^a}{x^b} = x^{a-b}: x2x3=x2(3)=x2+3=x1=x\frac{x^{-2}}{x^{-3}} = x^{-2 - (-3)} = x^{-2 + 3} = x^1 = x

For yy, use the same exponent rule: y0y3=y0(3)=y0+3=y3\frac{y^0}{y^{-3}} = y^{0 - (-3)} = y^{0 + 3} = y^3

So, the expression inside the parentheses becomes: 2xy32xy^3

Step 2: Apply the outer exponent

Now apply the exponent 3 to everything inside the parentheses: (2xy3)3=23x3(y3)3=8x3y9\left(2xy^3\right)^3 = 2^3 \cdot x^3 \cdot (y^3)^3 = 8x^3y^9

Final Answer:

8x3y98x^3y^9
