(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

Answer:
-64
Step-by-step explanation:
The question is asking to solve 
Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.
is the same as -4 · -4 · -4
First let's figure out if this will be negative or positive
Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive
Now find out what 4 x 4 x 4 equals (64)
In conclusion the answer is -64
