Option C:
is the value of a and b
Explanation:
Given that the expression 
We need to determine the value of a and b
Let us consider the term
and take the prime factorization of the term 648
Thus, we have,
648 divides by 2,

324 divides by 2,

162 divides by 2,

81 divides by 3,

27 divides by 3,

9 divides by 3,

Thus, we have,

Therefore, equating the powers of 2 and 3, we get,

Hence, the value of a and b is 3 and 4
Thus, Option C is the correct answer.
I believe it is A correct me if I’m wrong
The number of even positive integers less than a.b, i.e 90, is 45.
<h3>What are Arithmetic operations?</h3>
Arithmetic operations can also be specified by subtract, divide, and multiplying built-in functions.
Given that
a = 7 and b = 13
⇒ ab
Substitute the values of a and b in the above expression,
⇒ (7)(13)
⇒ 91
Since the number of even positive integers is less than
⇒ ab > even positive
⇒ 90 > even positive
since the even number less than a.b i.e. 91 is 90,
Here, 90 is the 45th number in the series of even positive numbers.
Thus, the number of even positive integer less than a.b, i.e 90, is 45

46-(-26)
= 46+26
= 72
As - and - together makes plus.
