To find 5, Beau found 22 = 4 and 32 = 9. He said that since 5 is between 4 and 9, 5 is between 2 and 3. Beau thinks a good estimate for 5 is 2 + 3 2 = 2.5. Is his estimate high or low? How do you know?

Complete question

To find , Beau found and . He said that since 5 is between 4 and 9, , is between 2 and 3. Beau thinks a good estimate for , is Is his estimate high or low? How do you know?

The estimation is high because 5 is very close to 4 so will also be very close to which is lower than the estimate

In order to get a good estimate

The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them

i.e

From here we can see that  lies between 2.2 and 2.3 but is closer to  2.2

So a good estimate for is 2.2

Step-by-step explanation:

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
