Question 599723: How would you simplify the radical expression( i will use R instead of a radical symbol):
R(12(x+4)^9) ?? I am not sure. I tried distributing the 12 to the x and the 4, but what would I do with the raised exponent 9? Please help me! thank you!

sqrt%28%2812%28x%2B4%29%5E9%29%29
Perhaps we can factor to reveal some perfect squares.

Extract the square root of each square
2%28x%2B4%29%28x%2B4%29%28x%2B4%29%28x%2B4%29%2Asqrt%283%28x%2B4%29%29
which is
2%28x%2B4%29%5E4%2Asqrt%283%28x%2B4%29%29
