Question

Ans this question. ​

Answer 1

Answer

Step-by-step explanation:

(x+1/x)²=x²+1/x²+2

(x+1/x)²=50/7+2

(x+1/x)²=50+14/7

(x+1/x)²=64/7

(x+1/x)=√64/7

(x+1/x)=8/√7

Answer 2

Answer:

answer is 8/√7

Step-by-step explanation:

here it is given that x^2+1/x^2=50/7

so (x+1/x)^2=x^2+1/x^2+2×x×1/x

•(x+1/x)^2=x^2+1/x^2+2

• ". =50/7 +2

• ". =(50+14)/7

• ". =64/7

•x+1/x. =√64/√7

• x+1/x. =8/√7

please ignore the shortcuts( " )this one

if u dont understand this it means the same as written above..
