Question

2) If x= 2+3 then
find x2 +1/x2​

Answer 1

Answer:

Given: x= 2+3 = 5

Find: x²+1/x²

= 5² + 1/5²

= 25 + 1/25

= 625/25 + 1/25

= 626/25

Else

Find: x×2+1/x×2

= 10+1/10

= 100/10 + 1/10

= 101/10

Step-by-step explanation:

Sorry, I cann't understand whether it is X² or X×2. So i have done both

Answer 2

Answer:

Given

       

                   $x= 2+3=5$

To Find

                    $x^2 + \frac{1}{x^2}$

       I think that you mean x2 as x²

Answer

 

                          x= 5

Therefore,

                  $5^2 +\frac{1}{5^2}$

              =  $25 + \frac{1}{25}$

             =  $\frac{625}{25} + \frac{1}{25}$

            =   $\frac{626}{25}$

           =   $25\frac{1}{25}$

          =   $25.04$

             

                -OR-

             If u mean x2 as 2 × x

Then Answer =

                            x= 5

Therefore,

               2x + $\frac{1}{2x}$            

              = 2×5 + $\frac{1}{2*5}$

             = 10 + $\frac{1}{10}$

            =  $\frac{101}{10}$    

           = 10.1
