Question

What expression is undefined

Answer 1

Step-by-step explanation:How do we know when a numerical expression is undefined? It is when the denominator equals zero. When we have a denominator that equals zero, we end up with division by zero. We can't divide by zero in math, so we end up with an expression that we can't solve.

Answer 2

To find:

Which of the four expressions are undefined, or not possible to calculate.

Steps:

Lets go through each option one by one

Option A:

`-(0)/(2)` , in this expression a negative zero is divided by 2, we know that zero divided by any number is equal to 0.

`-(0)/(2)= -0 = 0`

Since option A is defined. Now lets go to option B

Option B:

`(3)/(6-6)= (3)/(0)`

this expression shows 3 divided by a zero, but dividing any non-zero number by 0 is not possible.

Therefore option B is undefined. We found out the answer but lets continue for learning purposes.

Option C:

0 ÷ 11 =
`(0)/(11)`

This expression is similar to the first expression, where zero is divided by any number.

`(0)/(11) = 0`

Therefore option C is defined. Now let continue to option D

Option D:

`(-4+0)/(8)= (-4)/(8)= (-1)/(2)`

In this expression, the final answer after simplifying is -1/2 which is a number and is possible to calculate

Therefore option D is defined.
