(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

Step  3  :

Final result :

(15m – 4)2
