The answer should be positive, so there is no need to check for negative numbers.
Okay 👍
√(3+√(x+9)) =∛x3+√(x+9)=x^(2/3)√(x+9)=x^(2/3)-3x+9=x^(4/3)-6x^(2/3)+9x^(4/3)-x-6x^(2/3)=0〖let t= x^(1/3)〗t^2-t-6=0t=3 or-2x^(1/3)= 3 or-2x=27 or-8
Well done 👍
@@furqanminto thx,bro. you too.

√(3+√(x+9)) =∛x
3+√(x+9)=x^(2/3)
√(x+9)=x^(2/3)-3
x+9=x^(4/3)-6x^(2/3)+9
x^(4/3)-x-6x^(2/3)=0
〖let t= x^(1/3)〗
t^2-t-6=0
t=3 or-2
x^(1/3)= 3 or-2
x=27 or-8
Well done 👍
