Math Problem Statement

Simplify the expression: \(\frac{(x^3y^{-2})^3}{6x^{-9}}\). Write your answer without negative exponents.

Solution

The problem in the image appears to be about simplifying an expression. The expression is:

(x3y2)36x9\frac{(x^3y^{-2})^3}{6x^{-9}}

You are required to simplify this expression without using negative exponents. Let's break this down step by step:

Step 1: Apply the exponent rule (am)n=amn(a^m)^n = a^{mn}

For the numerator (x3y2)3(x^3y^{-2})^3, distribute the exponent 33 to both x3x^3 and y2y^{-2}:

(x3y2)3=x3×3y2×3=x9y6(x^3y^{-2})^3 = x^{3 \times 3}y^{-2 \times 3} = x^9y^{-6}

So, the expression becomes:

x9y66x9\frac{x^9y^{-6}}{6x^{-9}}

Step 2: Simplify the exponents of xx

Now, apply the quotient rule am/an=amna^m / a^n = a^{m-n} to simplify x9/x9x^9 / x^{-9}:

x9x9=x9(9)=x9+9=x18\frac{x^9}{x^{-9}} = x^{9 - (-9)} = x^{9 + 9} = x^{18}

So the expression is now:

x18y66\frac{x^{18}y^{-6}}{6}

Step 3: Convert negative exponent to positive

Finally, to remove the negative exponent on y6y^{-6}, write it as:

x186y6\frac{x^{18}}{6y^6}

This is the simplified expression without negative exponents.

The final answer is:

x186y6\boxed{\frac{x^{18}}{6y^6}}
