Question

How do i solve

8x^(2/3)-39x^(1/3)-5=0

Answer 1

`8 x^{ (2)/(3) } -39 x^{ (1)/(3) } -5=0`


`8 \sqrt[3]{ x^(2) } -39 \sqrt[3]{ x^(1) } - 5=0`


`8 \sqrt[3]{ x^(2) } -39 \sqrt[3]{ x } = 5`


`8( \sqrt[3]{ x^(2) } )^(3) -39( \sqrt[3]{ x })^(3) =5 ^(3)`


`8 x^(2) -39x =5 ^(3)`


`8 x^(2) -39x =125`


`8 x^(2) -39x - 125 = 0`

Hope this helps '-'
