Answer 2

4..So to make it a perfect square we need to multiply 175 and 7. Therefore 175 x 7 = 1225.

5..675= 3×3×3×5×5

6..2112.5 is the number.

7..To find the smallest number by which 9408 must be divided so that the quotient is a perfect square, we have to find the prime factors of 9408. Out of the prime factors of 9408, only 3 is without pair. So, 3 is the number by which 9408 must be divided to make the quotient a perfect square.

8..When we divide the 7220 by 8 then we will get the quotient as a perfect square.

9..Hence the required answer is 3×2=6.. On dividing 3750 by 6 we get 625 which is a perfect square.
