I just did this in my math class...
Okay so first we need to find the square root of 448. For this we need to find the largest perfect square that goes into 448, which is 64.(We know that 64*7=448) So we pull an 8 outside of the radical and we have a 7 remaining inside the radical. Our first part would be that the sq. root of 448 equals 8 root 7. Now we have x to the third power or x cubed. FRor this step we have to do the square root of x cubed which is x squared with an x still remaining inside the radical. Now...we have our final answer. :)Our answer is 8x(outside of the square root(radical)) and 7x (inside the radical). We are all finished. Contact me with any questions. :)
