Question

If 2 is the mean of P and 1/P then find the mean of p^2 and 1/p^2​

Answer 1

Step-by-step explanation:

First find the value of p using the first given clue

Mean of p and 1/p is 2

Means

(p+1/p)/2=2

P+1/p=4

P=4-(1/p)

P=(4p-1)/p

P^2=4p-1

Find the value of p in this quadratic equation

P^2-4p+1=0

After finding out the value of p using above equation

Substitute and check it if that

Mean of p and 1/p is 2

If the value of p satisfy that then

Put that p value in the

P^2+1/(p)^2

Equation and find out the value

P=4+2(3^0.5)/2
