Damn my lack of knowledge of these forums. The 1 is supposed to be above the x to the 3, as in a fraction.
I need to find the square root of the above equation.
I found this in one of my homework questions and even after looking through all my notes I can't figure this one out. Can anyone perhaps get me started? I don't want to ask for the final answer because that wouldn't help me, but I'd very much appreciate a little bit of direction.
Don't worry, it is equivalent.
So, you want to find . You can apply the rules of square roots, and we get :
Now, , so ...
Note that . By applying the laws of exponents, we have . Therefore :
If you wish to have a fraction-free result, remember that . Thus :
Does this make sense ? I tried to put as much help as I could, if you still have questions don't hesitate to ask. This can be applied to any such simplification problem.
