Please help me to solve this

Answer 1

Step-by-step explanation:

i hope this may be your required answer

Answer 2

Answer:

Key board has no such letters.

if this number is urgent,then I can only do a small help by explaining the way to solve.

Take a=x

and b=1/x

Given (a+b)=4

or (a+b)²=16

or a²+b²+2ab=16

Here ab=1

so calculate a²+b².

you get (ii) quest's answer.

Then put (a-b)²=a²+b²-2ab

Again ab=1 and put the value of a²+b²,

you get (i) answer

solve two equations,

one is a+b=4

and a-b=something

you get the value of a and b

then find a to the power 4 and b to the power 4,

Next put these value in quest.(iii)

You get answer.

If my technique satisfies anyone, then plz give me thanks.
