sqrt(x)+4 = 10;
sqrt(x) = 10-4;
sqrt(x) = 6;
x = 36

square root x + 4 = 10
It can be written as vx + 4 = 10
Squaring the both sides gives x + 4 = 100
x = 100 - 4 = 96

why is my answer incorrect? What I understood is the user meant the square root of (x and 4) while your understanding is that it's only the square root of x.

@yeswey, Although I am not good as you in mathematics, but in your way of solving it's answer should also be 36. Because, in your workout, if vx + 4 = 10 then vx = 10-4 = 6 and then x = 36.

I have checked it through the trusted online math calculator which also confirms the same answer. Please check my solution link and you will get the details.

Just because i did not add an parentheses there, and it did not recogonize by the calculator. Anyway, i think there are really ambiguity with such questions.

@yeswey, did you check this question through " ? It is a good online math calculator.
Added 4/21/2014 12:21:49 PM
yeswey, I think yours would only be correct if the question was square root of the sum of x and 4; or v(x+4)

@debnjerry, thanks for the good explanation. I am not good in maths as @yeswey but I have checked the answer thoroughly and then submitted.

Also, roots and exponents are evaluated before addition (when there are no brackets).

That makes point, thanks.
