+314 If the unit value of the square root of 17 is represented as x and its (sq root 17) decimal value is represented by y, x^2+(1/y)?
+118677 If the unit value of the square root of 17 is represented as x and its (sq root 17) decimal value is represented by y, x^2+(1/y)?
I will try and understand what you have said first.
\(x=\sqrt{17} = 17^{0.5}\\ y=\sqrt{\sqrt{17}}=17^{0.25}\\ x^2+\frac{1}{y}\\=17+\frac{1}{17^{0.25}}\\\approx 17+\frac{1}{2.0305431848689307}\\\approx17.4924790605054523308\)
+314 Sorry that it wasn't clear enough, I had to translate the question as best as I could from Chinese and naturally I'm not a native speaker of English! What I meant by the unit value was the number before the decimal point. 
+118677 Say a number is 6.126543
Then 6 is the floor value
OR
6 is the number rounded down to the nearest integer.
Just so you will know for next time

A question for someone else. Maybe Alan
What is the floor value of -6.5 [Or any number between -7 and -6]
I assume it is -7, is that correct ?
