Hello @All

There was some controversy in the 15th April puzzle. After discussing it with top maths professors the final result is that only option 5 is correct.

But all those users who answered with option 1 have been given the marks as well.

Below is the rule to understand square root problems. Please use the logic explained in the image below to solve this type of question in your exam but if user wants to go with their logic then it will be his/her choice. Our Moto is to give you a right answer for every question asked on our website.

Sqrt(36)-5 = ?

I think answer is only 1, not -11

Principle square root is sometimes called the positive square root.

MP 10 years ago

If u r a student of 8th standard, then this logic may be correct.But for normal mathematical calculations, u will have to consider both roots.
If this logic is accepted then solution of ax^2+bx+c=0
will be
x= (-b+root(b^2-4ac))/2a only
and
not
x= (-b +/- root(b^2-4ac))/2a.
you may not give marks but pls do not give illogical reasoning.

Can you please give the names and contact numbers of ' top maths professors' who justified that the final result is that only 'option 5' is correct? I do not think any mathematician can justify this logic.

Prerna 10 years ago

Dear Admin,
I think your logic will be harmful for the students/ members of this site as no mathematics teacher will agree with this logic.Please use this site for creating interest for maths and not to justify mistakes with such reasoning.
Every one knows
Sq root (x^2) =+/- x
and same logic is applicable in every situation.
This logic is applied only when u are getting non integer values for men/ boys/labor or -ve values for number of days/amount in some questions. There is no such situation here. Please read the question and apply mind while putting values in LHS and RHS and check whether u get LHS=RHS or not. Positive sq root may be principal sq root bit not only sq root.

@ MP,AMAN,PRERNA@ MP,AMAN,PRERNA
The solution to 15th april puzzle has 2 roots
x = 1,4
from this x = 1 is an extraneous solution.
an extraneous solution represents a solution, such as that to an equation, that emerges from the process of solving the problem but is not a valid solution to the original problem.
Please check the link below. I hope that it may clear your doubts.

Dipin is definitely right but you should be prepared to accept the 'logic' of so called intellectuals who have their own mindset.
Every body knows that
Sqrt (25) = +- 5 and not only +5.
If we consider
Sqrt (25) = - 5, then x=4 should also be wrong.

Such mistakes are common at this site. That is why I did not answer yesterday's puzzle. All the best for next puzzle.

Dear admin,
please check solution for puzzle dtd 15/4/14..

Sqrt(2x^2-2x+1)-2x+3 = 0
or 2x^2-2x+1=(2x-3)^2
or x^2-5x+4=0
or x = 1,4

please note that x=1 also satisfies the equation as sqrt (1) = +/-1
So when we consider sqrt 1 = -1 ,
we get
LHS=RHS

so correct ans is option 1 when x=1,4
Please do not make fun of Maths at this prestigious site.

Dear admin, please check solution for today's puzzle.

Sqrt(2x^2-2x+1)-2x+3 = 0
=> 2x^2-2x+1=(2x-3)^2
=> x^2-5x+4=0
=> x = 1,4

please note that x=1 also satisfies the equation as sqrt (1) = +/-1
So when we consider sqrt 1 = -1 it satisfies the condition. Hence ans should be x=1,4.. option 1
