Between which two whole numbers
is the square root of 11?
A. 1 and 2
B. 2 and 3
C. 3 and 4
D. 4 and 5

C

Step-by-step explanation: First, it's important to know our perfect squares.

I have attached the list of perfect squares for the numbers between 1 and 15.

Notice that 11 is not a perfect square since it's not on our list. However, the square root of 11 falls between the square root of 9 and the square root of 16.

To see this, we can simplify the square root of 9 to 3 and the square root of 16 to 4.

Now we can see that the square root of 11 is between 3 and 4.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
