## anonymous 4 years ago solve this equation please: x^3+27=0 a medal will be given!

1. anonymous

x^3=-27 x=-3

2. anonymous

x^3 = -27 x = -3

3. anonymous

$x ^{3}+27 = 0$ $x ^{3}=-27$ $\sqrt[3]{x}=-3$

there is no easy way to get a cube root, unless you are allowed to use a calculator. Without a calculator, it is a good idea to memorize a few of the smaller cubes: 1 1 2 8 3 27 4 64 5 125 10 1000

6. phi

these questions are to separate out people who go that extra mile...
