a) 9
b) 13
c) 49
d) none of these​

Answer 1

Answer:

d

Step-by-step explanation:

remaining numbers squares are not satisfy

Answer 2

Answer:

d

Step-by-step explanation:

1625 ÷x =y²

we have to find factors of 1625, in such a way that one factor is square

1625 = 5×325 = 5×5×65 =5×5×5×13

1625 = 25×65 =5²×65

1625 ÷ 65 =5²

x=65, y=5

1625 should be divided by 65 then quotient = 25 which is a perfect square
