Question

If a number is multiplied by 10, the resultant number is the square of the original number. Find the number.​

Answer 1

Answer:

Step-by-step explanation:

if the two numbers are  

a and b

so according to question

ab = a² = b⅓

so

a=b

and

ab⅔ = 1

so a=b=1

so only one pair is possible

i.e. (1,1)

Answer 2

Let the number be x. (obviously XD)

10x=x²

x=10x/x=10
