Find the value of ${1111}^2$ if:

$1^2=1$
${11}^2=121$
${111}^2=12321$

Q. Find the value of ${1111}^2$ if:

$1^2=1$
${11}^2=121$
${111}^2=12321$

Q.

Using the pattern 11² = 121 and 111² = 12321, we get 1111² =

Q. Look at the following pattern:
$1^2=1$
${11}^2=121$
${111}^2=12321$
${1111}^2=1234321$
${11111}^2=123454321$
Make a conjecture about each of the following:
${111111}^2=$
