ok there is a many confusion below soIwill watch if Ican help to straighten it the end for the is fairly important.
You are watching: What is the square root of 49
Firstly 7*7=49 and also (-7)*(-7)=49
-----------------------------------------------------
Now if the inquiry is $$sqrt49$$ then the price is 7 (Just 7 NOT -7)
This is due to the fact that if the square source is written right into the original question just the positive answer counts. The is a convention.
----------------------------------------------------
However, if the inquiry is
$$\x^2=49 qquad findquad x \\ $That is different due to the fact that the square source is no written right into the original question.$\\ x=pmsqrt47=pm7$$
---------------------------------------------------
Please, if you desire to questioning questions do so because this is important.

The convention is that us assume the optimistic root, unless we are fixing an equation...
So.... √49 = 7
But
x2 = 49
x = ±√49 = ± 7
