Question

How do you find the best whole-number ESTIMATE of √NUMBER

Answer 1

perfect square?

Answer 2

I guess...

Answer 3

if u round it off it is estmating a whole-number

Answer 4

so if you are asked to approximate the sqrt of 157
you will find the two perfect squares it is between
so in this case 12 and 13(12^2=144 and 13^2=169)
now you can just put 12.(something) as an approx., so about 12.5

Answer 5

well I just approximate

\[\sqrt{19}\]

between 4^2 = 16 and 5^2 = 25.... closer to 16 so I'd say 4.3 or 4.4

not much science to it.. bet it works...

Answer 6

So... √40
A. 6 <---
B. 7
C. 10
D. 20

6x6=36
7x7=49
10x10=100
20x20=400

36 is the closest to 36 without going over 40...

Answer 7

yep... thats the choice...

Answer 8

Yay! :)

Answer 9

good job
