prove that for each n in N, 1^3+2^3+...+n^3=[n(n+1)/2]^2

my dumb butt got "lost" in the wanting to prove p(k+1) is true (if that even makes sense, lol)
The equation being proven is 1^3+2^3+ +n^3=[n(n+1)/2]^2.
N represents the set of natural numbers, which are counting numbers starting from 1 (i.e. 1, 2, 3, ...).
The purpose of proving this equation is to demonstrate a mathematical relationship between the sum of cubes of natural numbers and the square of the sum of the same natural numbers.
This equation can be proven using mathematical induction, which involves showing that the equation holds for a base case (n=1) and then showing that if it holds for any arbitrary number k, it also holds for the next number (k+1).
This equation has implications in various fields of mathematics, including number theory, algebra, and calculus. It also has practical applications in solving problems related to sums of consecutive cubes and squares.
