Detailed Solution

We find the value of the expression given in each option and then check for the condition.
(1)

0 × 0

The product of the numbers when multiplied by zero will always be zero. Hence,

0 × 0 = 0

Here, the result is zero.
(2)

0 / 2

The division will always result in 0 when the numerator of the provided fraction is zero.
Since zero is a null value, we cannot divide it.

02 = 0

Here, the result is zero.
(3)

6 − 6 2

We obtain the result as zero after subtracting in the numerator, or (6-6). The outcome of division is always zero if the numerator of the supplied fraction is set to zero. Since zero is a null value, we cannot divide it.

6 − 6 2 = 02 = 0

Here, the result is zero.
(4) When we multiply any number by zero, the addition's outcome is unaffected by the zero addition.
One refers to this zero as having the additive identity attribute. 4+0=4
The outcome of this addition is therefore not zero.
From all the options, we get that only in option 4 the value of the expression is not zero.
Therefore, the correct option is 4.
