Question

Find the smallest number by which 2800 must be divided so that it becomes a perfect square.Also find the square root of number so obtained…​

Answer 1

Answer:

Hence, 2800 needs to be divided by 7 to become a perfect square. Thus, the required smallest whole number by which it should be divided so as to get a perfect square number is 7 and the square root is √400=

Answer 2

Answer:

the number should be divided by 7 to obtain a perfect square and the square root of the number is 20

Step-by-step explanation:

if we factorise 2800 we get 2 x 2 x 2 x 2 x 5 x 5 x 7

so we need to divide by 7 as it is the only single factor

then we get 2 x 2 x 2 x 2 x 5 x 5 = 400

and square root of 400 = 20
