Question

2_2 ans 0 from naman ​

Answer 1

Answer:

2-2=0

Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. Subtraction is signified by the minus sign, −. For example, in the adjacent picture, there are 5 − 2 peaches—meaning 5 peaches with 2 taken away, resulting in a total of 3 peaches.

Answer 2

Answer:

This is a misapplication of the product rule for square roots. The product rule is guaranteed to work only when both values are positive. When x = y = -1, the product rule may not apply, and as demonstrated, it is not a valid step because it leads to the conclusion that 2 = 0
