Final answer:

The value of the given expression can be calculated step by step to find that it can be written as k * 12¹⁰⁰¹, where k = 4(3¹⁰⁰¹)(4¹⁰⁰²).

Step-by-step explanation:

The value of the expression (3¹⁰⁰¹+4¹⁰⁰²)²-(3¹⁰⁰¹-4¹⁰⁰²)² can be calculated step by step:

(3¹⁰⁰¹+4¹⁰⁰²)² = (3¹⁰⁰¹)² + 2(3¹⁰⁰¹)(4¹⁰⁰²) + (4¹⁰⁰²)²

(3¹⁰⁰¹-4¹⁰⁰²)² = (3¹⁰⁰¹)² - 2(3¹⁰⁰¹)(4¹⁰⁰²) + (4¹⁰⁰²)²

Substitute these values back into the main expression:

(3¹⁰⁰¹+4¹⁰⁰²)²-(3¹⁰⁰¹-4¹⁰⁰²)² = (3¹⁰⁰¹)² + 2(3¹⁰⁰¹)(4¹⁰⁰²) + (4¹⁰⁰²)² - (3¹⁰⁰¹)² + 2(3¹⁰⁰¹)(4¹⁰⁰²) - (4¹⁰⁰²)²

Simplify the expression:

(3¹⁰⁰¹+4¹⁰⁰²)²-(3¹⁰⁰¹-4¹⁰⁰²)² = 4(3¹⁰⁰¹)(4¹⁰⁰²)

So, the expression can be written as k * 12¹⁰⁰¹, where k = 4(3¹⁰⁰¹)(4¹⁰⁰²).
