Question 4Fill out the boxes to demonstrate your understanding of estimating a non perfect square?Estimate V388 to the nearest whole number?V388АBCDEFFinal Estimate

Answer 1

For this problem we want to estimate:

`√(388)`

We need to take in count that this number is not a perfect square. And we can use the following definition:

The nearest perfect square to 388 is 361 because:

`√(361)=\text{ }√(19\cdot19)=19`

And replacing we have:

`√(388)=√(361)+(388-361)/(2√(361))=19+(27)/(2\cdot19)=19+(27)/(38)\text{ }`
`A=361,B=19,C=400,D=20,E=19,F=20`
