Question

Please Please help me! I have a problem I need solved, its adding a radical

Answer 1

just a sec and ill type it out equation form

Answer 2

\[-7\sqrt[3]{81}+\sqrt[3]{192}\]

Answer 3

\[\Large -7\sqrt[3]{81}+\sqrt[3]{192}\]



\[\Large -7\sqrt[3]{27*3}+\sqrt[3]{64*3}\]



\[\Large -7\sqrt[3]{27}\sqrt[3]{3}+\sqrt[3]{64}\sqrt[3]{3}\]



\[\Large -7*3\sqrt[3]{3}+4\sqrt[3]{3}\]



\[\Large -21\sqrt[3]{3}+4\sqrt[3]{3}\]



\[\Large (-21+4)\sqrt[3]{3}\]



\[\Large -17\sqrt[3]{3}\]



So \[\Large -7\sqrt[3]{81}+\sqrt[3]{192}=-17\sqrt[3]{3}\]

Answer 4

omg thank you! that was the correct answer :) I will look over carefully what you've done
