Answer 2

The possible value of a is 0.

GIVEN:- a x a=0

TO FIND:- value of a

SOLUTION:-

• 0 is a rational number because any number can be divided by 0 and equal to 0.
• 0 is the only rational number whose square is equal to 0 because other rational number squares are always more than 0.

According to the question a rational number (a) when squared gives the outcome as 0.

$a \times a = 0 \\ {a}^{2} = 0$

By square rooting both sides

$a = 0$

Hence, the possible value of a is 0.
