Question

If x^2+1/x^2=14, find the value of x^7+1/x^7

Answer 1

Answer:

first equation:

x^2+1/x^2= 14

x^2/x^2=14-1

x^2-2=13

x=13

second equation:

x^7+1/x^7

13^7+1/13^7

13^7-7 +1

1+1

Step-by-step explanation:

first, we have to move the +1 from LHS to RHS. Then we have to subtract the powers of x as both the bases are same and also subtract 14-1 . after that you get the value of x .after that,place the value of x in x^7+1/x^7 and solve the equation
