Answer 1

hey mate.
here's the solution

Answer 2

Answer:

e) 39

Step-by-step explanation:

Since we are given that we need to find which number should be added to 1330 to make it perfect square .

Option a) 56

1330+56 = 1386

Now $\sqrt{1386} = 37.229$

Hence not a perfect square .

Thus Option A is wrong.

Option b) 1

1330+1 = 1331

Now $\sqrt{1331} = 36.48$

Hence not a perfect square .

Thus Option B is wrong.

Option c) 41

1330+41 = 1371

Now $\sqrt{1371} = 37.02$

Hence not a perfect square .

Thus Option C is wrong.

Option d) 30

1330+30 = 1360

Now $\sqrt{1360} = 36.8$

Hence  not a perfect square .

Thus Option D is wrong.

Option e) 39

1330+39 = 1369

Now $\sqrt{1369} = 37$

Hence a perfect square .

Thus Option E is right.
