Question

Which expression is undefined​

Answer 1

Answer:

The expression $8\div0$ is undefined.

Solution:

Considering the given equations,

• $-8\div (-8) = 1$
• $-8\div8 = (-1)$
• $0\div8 =0$
• $8\div0$ is undefined

The expression is undefined because of the following reason.

Consider the expression $y =8\div 0$

Here, if y equals 8 divided by 0 then y times 0 should also be 0 but it is not possible except in the situation when both the dividend and divisor is 0.

So, the expression  $8\div0$ can be stated as undefined.
