Question

Find the least number which must be added to 6412 so as to get a

perfect square. Also, find the square root of the perfect square so obtained​

Answer 1

Answer:

149&81.

Step-by-step explanation:

square of 81 is 6561.

so,6561-6412=149

149 must be added to 6412 so as to get perfect square.

square root =81

Answer 2

Given number = 6412

Given number = 6412Finding the nearest root is 80

Given number = 6412Finding the nearest root is 8080^{2} = 6400802=6400 which is less than 6412

Given number = 6412Finding the nearest root is 8080^{2} = 6400802=6400 which is less than 6412We take the next number 81^{2} = 6561812=6561

Given number = 6412Finding the nearest root is 8080^{2} = 6400802=6400 which is less than 6412We take the next number 81^{2} = 6561812=6561Therefore, 6561 - 6412 = 1496561−6412=149

Given number = 6412Finding the nearest root is 8080^{2} = 6400802=6400 which is less than 6412We take the next number 81^{2} = 6561812=6561Therefore, 6561 - 6412 = 1496561−6412=149Therefore, the required number = 149

Given number = 6412Finding the nearest root is 8080^{2} = 6400802=6400 which is less than 6412We take the next number 81^{2} = 6561812=6561Therefore, 6561 - 6412 = 1496561−6412=149Therefore, the required number = 1496412 + 149 = 65616412+149=6561 which is a perfect square

Given number = 6412Finding the nearest root is 8080^{2} = 6400802=6400 which is less than 6412We take the next number 81^{2} = 6561812=6561Therefore, 6561 - 6412 = 1496561−6412=149Therefore, the required number = 1496412 + 149 = 65616412+149=6561 which is a perfect squareThe perfect square is the number which is obtained on multiplying the same number two times.
