Explanation:
Undefined expression--
It is a expression which is meaningless.
In real numbers if we divide a non-zero number by 0 then the expressions becomes meaningless.
1)
-8÷(-8)
On dividing the non-zero number by the number itself we get the resultant as 1.
i.e.
-8÷(-8)=1
2)
-8÷8
On dividing a number by the negative of same number we get the resultant as: -1
3)
0÷8
On dividing zero by any non-zero number we get the resulting value as 0.
i.e.
0÷8=0
4)
8÷0
Here in the denominator we have the number as zero.
Hence, the expression is undefined.
