c.+3
d.+or-0.01

Answer 2

\[\sqrt{.0009}=\sqrt{\frac{9}{10000}}=\frac{\sqrt{9}}{\sqrt{10000}}=\frac{\sqrt{3^2}}{\sqrt{10^3}}\]
That should be a good hint :)

Answer 3

and since it says square roots just do plus or minus in front of that

Answer 4

I got plus or minus .3

Answer 5

oops that was suppose to be 10^4 my bad

Answer 6

\[\frac{\sqrt{3^2}}{\sqrt{10^4}}=\frac{3}{10^2}=\frac{3}{100}\]

Answer 7

myininaya. i think when they post some thing like this
\[x^2 =4\]

then we write + or - before sqrt(a)

but when it asks
\[x = \sqrt{4}\]

then we write only +2 as the answer.

i donno why, although it means pretty much the same right??

Answer 8

i meant sqrt(4) instead of sqrt(a) over there.
