A) 10
B) 100
C) 144
D) 12

Answer 1

The square root of a gross (144) is 12. This is because 12 squared equals 144, and squaring and finding the square root are inverse operations.

Step-by-step explanation:

The question asks us to find the square root of a gross. In mathematics, a gross refers to a group of 144 items. To find the square root of a gross, we are looking for a number that when multiplied by itself equals 144. The square root of 144 is 12, so the correct answer is D) 12.

It can also be helpful to remember that squaring a number and finding the square root are inverse operations. For example, 12 squared (12²) equals 144, so the square root of 144 (√144) must be 12. This demonstrates the concept of integer powers and their significance in solving equations involving unknowns squared.
