4 + cube root of x = 129 (-4 from both sides to get rid of the 4)
cube root of x = 125
x = 125 cubed
x = 1953125
to check it just find the cbe root of 1953125 which is 125
:)

cube root(x) =125 so x= 125^3 =1,953,125
1,953,125^1/3 +4 = 125+4=129

4 + x^(1/3) =129
=> x^(1/3)= 129 -4
=> x^(1/3)=125
=>x= (125)^3
=>x=1953125
is it understandable to u?

4 + x^(1/3) = 129.
x^(1/3) = 125 = 5³.
Now cube both sides.
We get x = 5^9 = 1953125.
