The image contains a mathematical expression that appears to be a recurrence relation or a sum, along with a question in Spanish asking if the result is true or false.

The expression given seems to define a series $P(n)$ as:

$P(n) = 1^3 + 2^3 + 3^3 + \dots + n^3 = \left(\frac{n(n+1)}{2}\right)^2$

The question asks if the provided equation is true, which implies whether the sum of cubes of the first $n$ natural numbers equals the square of the sum of the first $n$ natural numbers.

Analysis:

• The sum of cubes of the first $n$ natural numbers is indeed given by: $1^3 + 2^3 + 3^3 + \dots + n^3 = \left(\frac{n(n+1)}{2}\right)^2$
• The right-hand side of the equation represents the square of the sum of the first $n$ natural numbers.

This is a well-known identity in mathematics, and it is correct.

Conclusion:

The statement in the image is True.
