To solve the equation \( \sqrt[3]{x+8}=-4 \), we first cube both sides to eliminate the cube root, giving us \( x + 8 = (-4)^3 \), which is \( x + 8 = -64 \). Next, we isolate \( x \) by subtracting 8 from both sides, leading to \( x = -64 - 8 \), resulting in \( x = -72 \). So your solution is spot on! Cubing the negative value might seem tricky, but remember: when you raise a negative number to an odd power, the result stays negative. This helpful reminder can prevent common mistakes when handling cube roots and powers in equations!
