Option D: 
is the product of the expression
Explanation:
The expression is 
We need to determine the product of the expression.
To determine the product of the expression, we need to simplify the given expression.
Thus, we have,
The term 
is of the form 
Now, we shall use the identity, 
Hence, we have,
Multiplying the terms and cancelling the common terms, we get,
Hence, the product of the given expression is
Therefore, Option D is the correct answer.

Answer:
-60
Step-by-step explanation:
Given the expression
5- {2*[(-5power2) -7 ] /3}
= 5- {2*[(25) -7 ] /3}
= 5- {2*[18 ] /3}
= -5 [2*6]
= -5(12)
= -60
Hence the required answer is -60
