The correct answer should be A) 25 since 25 * 25 * 25 = 15,625
25 * 25 = 625
626 * 25 = 15,625
I hope this helps.

Answer:
27
Step-by-step explanation:
Given expression :  
     1 + 24 + ( + 3) = 1
Bring the number 1 to the left side of the equal sign. The positive 1 becomes negative 1 when brought towards the left side of the equal sign.
1 + 24 + ( + 3) - 1 = 0
Now, opening the bracket, we get
1 + 24  + 3 - 1 = 0
Negative 1 and positive 1 will get cancel 
24  + 3  = 0
or 27
Therefore, the value of the numerical expression  1 + 24 + ( + 3) = 1 is 27.
