Step-by-step explanation:

=144-1

=143-3

=140-5

=135-7

=128-9

=119-11

=108-13

=95-15

=80-17

=63-19

=44-21

=23-23

=0

Count the Number of steps:

It evaluates to 12, giving us the answer

Answer 2

$\sqrt{144}$

$144 - 1 = 143$

$143 - 3 = 140$

$140 - 5 = 135$

$135 - 7 = 128$

$128 - 9 = 119$

$119 - 11 = 108$

$108 - 13 = 95$

$95 - 15 = 80$

$80 - 17 = 63$

$63 - 19 = 44$

$44 - 21 = 23$

$23 - 23 = 0$

$\sqrt{144} = 12$
