Answer 1

hey mate

here is the answer...

Answer:

x=5⅓+5^-⅓

multiplying throughout by 5⅓.

thus,

5⅓x=5⅓(5⅓+5^-⅓)

5⅓x=5⅓*5⅓+5⅓*5^-⅓

5⅓x=5⅔+5°

5⅓x=5⅔+1

5⅓x-5⅔=1

cubing both sides,

(5⅓x-5⅔)³=1³

(5⅓x)³-(5⅔)³-3*5⅓x*5⅔(5⅓x-5⅔)=1

5x³-5²-3*5¹x(1)=1

5x³-25-15x=1

5x³-15x=1+25

5x³-15x=26 (answer)

(b) is the correct option...
