Question

the least number to be subtracted from 743 to get a perfect square is

Answer 1

Given,

Base number = 743

Condition of the final number = A perfect square and less than the base number.

Solution,

Now if we follow the perfect square multiplication table (eg. 20×20,21×21 and so on),then we will get the the square of 27 is the answer which satisfies all the given criteria.

Because,

= (27)²

= 729 (it's a perfect square and less than the base number)

So,the difference with the base number = (743-729) = 14

Hence,we have to subtract 14 from 743 to get a perfect square.

Answer 2

Answer:

14

Step-by-step explanation:

14 should be subtracted from. 743 to make it a perfect square of 27
