Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

             100          
  ((102) -  (——— • 2)) -  -3
             52           

Step  2  :

            100
 Simplify   ———
            52 

Raising to a Power :

 2.1      Canceling out  5² as it appears on both sides of the fraction line

Equation at the end of step  2  :

  ((102) -  (4 • 2)) -  -3

Step  3  :

 3.1     10 = 2•5

(10)² = (2•5)² = 2² • 5²

Equation at the end of step  3  :

  ((22•52) -  8) -  -3

Step  4  :

Final result :

  95
