so 5n^3 - 230=90 first you add 230 to both sides so you get 5n^3=320 than you divide 5 from both sides so you get n^3=64 so you take the cube root of both sides to get the answer... n=4
[tex]5n^3-230=90[/tex]
[tex]5n^3=320[/tex]
[tex]n^3= \frac{320}{5} [/tex]
[tex]n^3=64[/tex]
[tex]n= \sqrt[3]{64} [/tex]
[tex]n=4[/tex]
