To solve for \( x \) in the equation \( \sqrt[3]{2 x+4}+5=9 \), start by isolating the cube root. Subtract 5 from both sides to get: \[ \sqrt[3]{2 x+4} = 4 \] Next, cube both sides to eliminate the cube root: \[ 2 x + 4 = 4^3 \] Calculating \( 4^3 \) gives us 64: \[ 2 x + 4 = 64 \] Now, subtract 4 from both sides: \[ 2 x = 60 \] Finally, divide both sides by 2 to solve for \( x \): \[ x = 30 \] So, the solution is \( x = 30 \).
