Question

The value of

$(111111{)}^2$

• A. 12345654321
• B. 12345432169
• C. 12376589431
• D. 13243563429

Answer 1

Answer: (A)

Lets observe the following pattern,

$1^2=1$

${11}^2=121$

${111}^2=12321$

${1111}^2=1234321$

Now, lets check $(111111{)}^2$

Since, it contains $6$ ones, it will increase from $1$ to $6$ and then decrease to $1$.
The value of $(111111{)}^2=12345654321$

Hence, Option A is correct.
