Solution - Simplification or other simple results

Step  1  :

 1.1     20 = 22•5

(20)²⁵ = (2²•5)²⁵ = 2⁵⁰ • 5²⁵

Equation at the end of step  1  :

  (2012) • (250•525)

Step  2  :

 2.1     20 = 22•5

(20)¹² = (2²•5)¹² = 2²⁴ • 5¹²

Equation at the end of step  2  :

  (224•512) • (250•525)

Step  3  :

Multiplying exponents :

 3.1    2²⁴  multiplied by  2⁵⁰   = 2^{(24 + 50)} = 2⁷⁴

Multiplying exponents :

 3.2    5¹²  multiplied by  5²⁵   = 5^{(12 + 25)} = 5³⁷

Final result :

  (274•537)
