Sagot :

Let's simplify the given expression step by step.

The given expression is:

[tex]\[ \frac{\left(2 x^2 - 5 y\right)^4}{\left(3 x^5\right)^3} \][/tex]

First, let's rewrite both the numerator and the denominator to understand each part separately.

### Step 1: Rewrite the numerator

The numerator is [tex]\(\left(2 x^2 - 5 y\right)^4\)[/tex]. This expression is already in its simplified form, so there's no need to make any changes here.

### Step 2: Rewrite the denominator

The denominator is [tex]\(\left(3 x^5\right)^3\)[/tex]. We can simplify this expression by applying the exponent rule [tex]\((a^m)^n = a^{m \cdot n}\)[/tex]:

[tex]\[ (3 x^5)^3 = 3^3 \cdot (x^5)^3 \][/tex]

Calculating the powers, we get:

[tex]\[ 3^3 = 27 \quad \text{and} \quad (x^5)^3 = x^{5 \cdot 3} = x^{15} \][/tex]

Thus, the denominator simplifies to:

[tex]\[ 27 x^{15} \][/tex]

### Step 3: Combine the simplified numerator and denominator

Now, we can write the simplified fraction:

[tex]\[ \frac{(2 x^2 - 5 y)^4}{27 x^{15}} \][/tex]

Putting it all together, the simplified form of the given expression is:

[tex]\[ \frac{(2 x^2 - 5 y)^4}{27 x^{15}} \][/tex]

This is the simplified version of the expression.
