What is the product of the square root of 121 and the square root of 36?

To find the product of the square root of 121 and the square root of 36, start by calculating each square root individually. The square root of 121 is 11, because 11 multiplied by itself equals 121. Similarly, the square root of 36 is 6, as 6 times 6 equals 36.

Now, multiply these two results together:

11 multiplied by 6 equals 66.

Therefore, the correct answer is 66, demonstrating that you can find the product of square roots using the individual square roots first, which simplifies the process of multiplication. This approach illustrates the properties of square roots and highlights the relationship between squares and their roots in arithmetic calculations.
