plz explain?
OpenStudy (brooke..help00):
You have to find the square roots. The first one is C. so find the numbers that you can multiply by them selves such as 2x2=4 and 4 1/2 x 4 1/2= 9
OpenStudy (rainbow_rocks03):
and what about 2,3,4
OpenStudy (wholock):
Because the square root of 8 is 2.82, the square root of 4 is 2 and the square root of 9 is 3, so that means the they would be the answer, to find the estimate, find the perfect square root on either side, which in the case of 8 is 4 and 9
OpenStudy (wholock):
2 is 36 and 49

3 is D. -9.5
OpenStudy (wholock):
And then for the last one you simple find the square root of 52, which is roughly 7.2, making the answer 7 feet.
OpenStudy (rainbow_rocks03):
THX
OpenStudy (rainbow_rocks03):
is it ok if I have for more?
OpenStudy (wholock):

Okay, well this should be easy, to estimate a non-perfect square root, you use the nearest perfect ones, so for 5, you would use 4 and 9 once again.
OpenStudy (wholock):
Number 1 is C.
OpenStudy (brooke..help00):
@Wholock I need your help:/
OpenStudy (wholock):
Number two, use the nearest perfect square roots, which are 36 and 49, 6 and 7 respectively. Since 45 is closer to 49, I would go with 7
OpenStudy (wholock):
@brooke..help00 Let me finish this and I'll be right with you.

Number 3 is C, because the negative square root of 66 is -8.2, which rounds to 8
OpenStudy (rainbow_rocks03):
ohh
OpenStudy (wholock):
The square root of 3 is 1.7, but they want an estimate, so I'd pick 2, or d.
OpenStudy (wholock):
The square root of 123 is inbetween the square root of 121, which is 11, and 144 which is 12, since 123 is closer to 121, I'd say 7
OpenStudy (wholock):
Okay, @brooke..help00 how can I help you!
