Question

Find the smallest number by which each of the given numbers must be multiplied so that the product is a perfect square. Also find the square root of this new number. (i) 175 (ii) 325 (iii) 720 (iv) 3150 ​

Answer 1

Answer:

175 = 7

325 = 13

720 = 5

3150 = 14

Step-by-step explanation:

As we need to find perfect squares we will take group of 2 numbers

Factors of 175 = 5×5×7

hence smallest number to be multiplied is 7

Factors of 325 = 5×5×13

hence smallest number to be multiplied is 13

Factors of 720 = 2×2×2×2×3×3×5

hence smallest number to be multiplied is 5

Factors of 3150 = 2×3×3×5×5×7

hence smallest number to be multiplied is 2×7=14
