Question

If f(x) = x² +1/x then find f(root 2)​

Answer 1

Answer:

f(x)= x^2 +1/x

f(√2)=^2+ 1/√2

= 2+1/√2

Answer 2

Answer:

Root 2

Step-by-step explanation:

f (x) = x ^2 + 1/ x

f (x) = x ^2 + 1/ x f ( root 2 ) = root 2 ^2 + 1/ root 2

f (x) = x ^2 + 1/ x f ( root 2 ) = root 2 ^2 + 1/ root 2f ( root 2 ) = 2 + 1 / root 2

f (x) = x ^2 + 1/ x f ( root 2 ) = root 2 ^2 + 1/ root 2f ( root 2 ) = 2 + 1 / root 2f ( root 2 ) = 2 + root 2 / 2 { by rationalising the denominator }

f (x) = x ^2 + 1/ x f ( root 2 ) = root 2 ^2 + 1/ root 2f ( root 2 ) = 2 + 1 / root 2f ( root 2 ) = 2 + root 2 / 2 { by rationalising the denominator }f ( root 2 ) = 4 + 2 root 2 / 2

f (x) = x ^2 + 1/ x f ( root 2 ) = root 2 ^2 + 1/ root 2f ( root 2 ) = 2 + 1 / root 2f ( root 2 ) = 2 + root 2 / 2 { by rationalising the denominator }f ( root 2 ) = 4 + 2 root 2 / 2By taking 2 common we get ,

f (x) = x ^2 + 1/ x f ( root 2 ) = root 2 ^2 + 1/ root 2f ( root 2 ) = 2 + 1 / root 2f ( root 2 ) = 2 + root 2 / 2 { by rationalising the denominator }f ( root 2 ) = 4 + 2 root 2 / 2By taking 2 common we get ,f ( root 2 ) = 2 ( root 2 ) / 2

f (x) = x ^2 + 1/ x f ( root 2 ) = root 2 ^2 + 1/ root 2f ( root 2 ) = 2 + 1 / root 2f ( root 2 ) = 2 + root 2 / 2 { by rationalising the denominator }f ( root 2 ) = 4 + 2 root 2 / 2By taking 2 common we get ,f ( root 2 ) = 2 ( root 2 ) / 2 f ( root 2 ) = root 2
