Question

If 10A x 3 = 31A, then A is given by
a) 0
b) 3
c)5
c)1​

Answer 1

Answer:

a)0

Step-by-step explanation:

because if you observe carefully you can see that the product of two different numbers from a same number is equal which is only possible when the second number is 0.

10A×3=31A

30A=31A=>30=31 which we know is fundamentally wrong.

this happens because A can only be zero and to cancel it from both sides mean dividing both sides by zero which is an indeterminate.

Answer 2

Answer:

a)0 is the right answer .
