Question

Solve.
^3√(3x+4)+6=7
(Not sure how to type a cube root, but that's what it is. Help.)

Answer 1

thats readable.

cbrt(3x+4) is workable as well; or 3rt(arg)

Answer 2

\[\sqrt[3]{3x+4}+6=7\]\[\sqrt[3]{3x+4}=7-6=1\]\[3x+4=1^{3}=1\]\[3x=1-4=-3\]\[x=-3/3=-1\]

Answer 3

subtract 6 from each side; cube it all to undo the cbrt and finish off to get to the x

Answer 4

then dbl chk lol

Answer 5

Thanks to you both! :)
