Solve 4=∛(x+2)+8

OpenStudy (anonymous):

is this your equation? \[\large 4=\sqrt[3]{x+2}+8\]

OpenStudy (anonymous):

Yes.

OpenStudy (anonymous):

subtract 8 from both sides then raise each side to 3 power what's the resulting equation now?

OpenStudy (anonymous):

I got to \[-4=\sqrt[3]{x+2}\] But I don't know what to do after.

OpenStudy (anonymous):

cube both sides.... on the right side you'll have x+2.

OpenStudy (anonymous):

what do you have on the left side?

OpenStudy (anonymous):

-64?

OpenStudy (anonymous):

good.. so now you have : -64 = x+2

OpenStudy (anonymous):

So, that's the answer?

OpenStudy (anonymous):

what's the answer?

OpenStudy (anonymous):

you said to solve for x...

OpenStudy (anonymous):

x=-66?

OpenStudy (anonymous):

there it is... :)

OpenStudy (anonymous):

Thank you so much :)
