Answer 1

Answer:

x=27 and x=-64 is the solution for the question

Answer 2

Step-by-step explanation:

let u=x^1/3

and u^2=x^2/3

now,

this can be written as,

u^2+u-12=0

u^2+4u-3u-12=0

u(u+4)-3(u+4)=0

(u-3)(u+4)=0

u-3=0

u=3

x^1/3=3

x=3^3

therefore x=27

and,

u+4=0

u=-4

x^2/3=4

x=-64

therefore x= -64ans..
