%28x%2B4%29%5E%282%2F3%29=4 Start with the given equation


%28x%2B4%29%5E2=64 Cube both sides. This will eliminate the denominator 3 from the exponent


x%2B4=8 Take the square root of both sides



x=8-4Subtract 4 from both sides


x=4 Combine like terms on the right side

Answer:
So our answer is x=4
