yea 144 is a perfect square

To determine which number is a perfect square, we need to find the square root of each option and check if it is a whole number. The square root of a number is a value that, when multiplied by itself, gives the original number.

Let's calculate the square roots of the given options:

A. The square root of 32 is approximately 5.6568. Since it is not a whole number, 32 is not a perfect square.
B. The square root of 144 is 12. 12 multiplied by itself is equal to 144. Therefore, 144 is a perfect square.
C. The square root of 1000 is approximately 31.6228. Since it is not a whole number, 1000 is not a perfect square.
D. The square root of 36000 is exactly 60. 60 multiplied by itself is equal to 36000. Therefore, 36000 is a perfect square.

Hence, the answer is:

B. 144
