Answer 2

Answer:

It is undefined.

Step-by-step explanation:

The expression is \color{#D61F06}{\textbf{undefined}}undefined.

Here's why:

Remember that \frac{a}{b}  

b

a

​  

 means "the number which when multiplied by bb gives a.a." For example, the reason \frac{1}{0}  

0

1

​  

 is undefined is because there is no number xx such that 0 \cdot x = 1.0⋅x=1.

The situation with \frac{0}{0}  

0

0

​  

 is strange, because every number xx satisfies 0 \cdot x = 0.0⋅x=0. Because there's no single choice of xx that works, there's no obvious way to define \frac{0}{0}  

0

0

​  

, so by convention it is left undefined. _\square
