Question

find the least number which must be subtracted from each of the following numbers so as to get a perfect square . also find the square root of perfect square so obtained (i)1989 (ii)3250

Answer 1

Step-by-step explanation:

Also find the square root of the perfect square so obtained. (i) 402 (ii) 1989 (iii) 3250 (iv) 825(v) 4000. So, if we subtract 2 from 402, we get a perfect square and square root of the perfect square will be 20. So, if we subtract 53 from 1989, we get a perfect square and square root of the perfect square will be 44.
