peut tu me résoudre ça

Simplifiez l'expression suivante : (x^5 / 3) / (9 / x^2)

Solution

Let's simplify the expression from the image step by step:

The given expression is:

x539x2\frac{\frac{x^5}{3}}{\frac{9}{x^2}}

Step 1: Invert and multiply the denominator.

When dividing by a fraction, we multiply by its reciprocal:

x53×x29\frac{x^5}{3} \times \frac{x^2}{9}

Step 2: Multiply the numerators and denominators.

Now, multiply the numerators and the denominators separately:

x5x239=x5+227=x727\frac{x^5 \cdot x^2}{3 \cdot 9} = \frac{x^{5+2}}{27} = \frac{x^7}{27}

Final Answer:

The simplified expression is:

x727\frac{x^7}{27}
