B. 13

Step-by-step explanation:

The given expression :

Using PEDMAS → parenthesis , exponents , divide , multiply , add ,subtract.

Use these operation in order in the given expression.

 [(+)(-)=(-)]

   [(-)(-)=(+)]

Therefore, the answer to the given expression is 13.

hence, the correct answer is option B. 13.

a² + b²= c²

24² + 7² = c²

c= 25

b) 1/3 * 1/5

step-by-step explanation:
