Your question implies there are choices given with possible answers. As I do not have those in front of me, I will show you how to simplify the radical. It is likely that the answer you seek is the simplified radical.
To simplify
we use the following identity: for positive values of a and b,
That identity allows us to re-write what we are given as
. Let us now consider each of these separately.
Though 50 is not a perfect square it can be written as 25 x 2 and 25 is a perfect square. Thus, we obtain
Next we consider
which is a perfect square as it is equal to
. Thus,
Lastly, we consider
which can be written as
and since
is a perfect square we obtain the following:
Putting that all together we obtain
Answer:
Jack should add more
Step-by-step explanation:
Because four eighth is half
And he only added 3/8
So when he adds 1/8 more the sum becomes 4/8
