a^3 + b^3 = 1000 - 3(21)(10) = 1000 - 630 = 370 - ECD Germany

Understanding the Context

The Mathematical Identity: Sum of Cubes

The left-hand side of the equation, a³ + b³, is a classic algebraic form governed by the identity:
a³ + b³ = (a + b)(a² – ab + b²)
However, in this instance, instead of factoring further, we start by computing the right-hand side:
1000 – 3 × 21 × 10 = 1000 – 630 = 370
So, we confirm:
a³ + b³ = 370

Solving the Equation: Finding Integer Solutions

To find values of a and b that satisfy a³ + b³ = 370, let’s explore small integer values since the cube values grow quickly.

• 7³ = 343
  
• 6³ = 216
  
• 5³ = 125
  
• 4³ = 64
  
• 3³ = 27
  
• 2³ = 8
  
• 1³ = 1

Now test combinations:

• a = 7 (343), b = ?
  Then b³ = 370 – 343 = 27 → b = 3
  ✔ This works: 7³ + 3³ = 343 + 27 = 370

Key Insights

• Other small cubes exceed or fall short:
  6³ + 5³ = 216 + 125 = 341 < 370
  No other integers between 1 and 7 yield exact sums to 370.
