myininaya · Answer

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

myininaya · Answer

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

anonymous · Answer

I got plus or minus .3

myininaya · Answer

oops that was suppose to be 10^4 my bad

myininaya · Answer

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

apoorvk · Answer

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??

apoorvk · Answer

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