Question

the number of digits in a number is x, find the possible number of digits in the square of that number​

Answer 1

Step-by-step explanation:

it is a formula

2n-1or 2n

eg:-2²=4(2n-1)

6²=36(2n)

Answer 2

the possible number of digits in the square of that number​ 2x or 2x - 1

Step-by-step explanation:

The number of digits in a number is x,

Then the possible number of digits in the square of that number​

are  2x  or  2x-1

Let say number

1  , 2 , 3   x = 1

Square are 1  , 4  , 9      , 1 Digit

2x - 1  = 1

4 to 9  x = 1

squares are 16 to  81  are 2 Digit

2x = 2

21² = 441

2 Digit  /  3 Digit

2x - 1 = 3

90² = 8100

2 Digit   4 Digit

2x = 4  

the possible number of digits in the square of that number​ 2x or 2x - 1
