  ((224•524) • 5) -  -1990

Step  2  :

Multiplying exponents :

 2.1    5²⁴  multiplied by  5¹   = 5^{(24 + 1)} = 5²⁵

Equation at the end of step  2  :

  (224•525) -  -1990

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   2²⁴ • 5²⁵ + 1990  =   10 • (1 + 199) 

Final result :
