    Answer:

    (3m-4/5)2  

    Final result :

     (15m – 4)2

     ——————————

         52    

    Step by step solution :

    Step  1  :

               4

    Simplify   —

               5

    Equation at the end of step  1  :

            4

     (3m –  —)2

            5

    Step  2  :

    Rewriting the whole as an Equivalent Fraction :

    2.1   Subtracting a fraction from a whole

    Rewrite the whole as a fraction using  5  as the denominator :

              3m     3m • 5

        3m =  ——  =  ——————

              1        5    

    Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

    Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

    Adding fractions that have a common denominator :

    2.2       Adding up the two equivalent fractions

    Add the two equivalent fractions which now have a common denominator

    Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

    3m • 5 – (4)     15m – 4

    ————————————  =  ———————

         5              5    

    Equation at the end of step  2  :

     (15m – 4)

    (—————————)2

         5    

    Step  3  :

    Final result :

     (15m – 4)2

     ———

         52
