Answer 1

Answer:

x²+1/x²=3 and

x⁴+1/x⁴=7

Step-by-step explanation:

x+1/x=√5-------------------(1)

Squaring the (1) equation, we get

(x+1/x)²=(√5)²

(x)²+(1/x)²+2*x*1/x=5  [(a+b)²=a²+2ab+b²]

x²+1/x²+2=5

x²+1/x²=5-2

x²+1/x²=3 ----------------(2)

Squaring the (2) equation, we get

(x²+1/x²)²=(3)²

x⁴+1/x⁴+2*x²*1/x²=9  [(a+b)²=a²+2ab+b²]

x⁴+1/x⁴+2=9

x⁴+1/x⁴=9-2

x⁴+1/x⁴=7
