Plz help will give y

√40 = 6.32, √75 = 8.66, √90 = 9.49

Step-by-step explanation:

Step 1: Find which integers the square root is between

√36 ∠ √40 ∠ 49

  6  ∠ √40 ∠ 7

Step 2: Estimate what the tenth place should be

Use trial and error after you estimate.  

40 is closer to 36 than it is to 49 so the tenth place has to be <5.

Let's try 3: (6.3)² = 39.69

The square is less < 40, so move on to the next step.

If the square was >40, then try the digit before 3.  Keep decreasing the number until you square is < 40.

Step 3: Repeat step 2 for the hundredths place

39.69 is just a little below 40, so let's try 2

(6.32)² = 39.94

Let's see if we can get closer to 40, let's try 3

(6.33)² = 40.0689

39.94 is closer to 40 than 40.0689 so the final answer is: 6.32
