Question

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

is the solution only 27?

Answer 1

-1/27 i think too

Answer 2

let x^ (1/3) = y
then x^(2/3) = y^2

Answer 3

so we have the equation
3y^2 - 8y - 3 = 0

can you solve this for y?

Answer 4

y=3, -1/3

Answer 5

yes

now you need to
solve 3 = x^(1/3)

and -1/3 = x^(1/3)

Answer 6

just cube both sides of the equations

Answer 7

x=27

Answer 8

and x=-1/27?

Answer 9

yes and ?

Answer 10

yes 27 , -1/27
