Question 679231: Use radical notation to rewrite the expression and then simplify, if possible: (49/25)^3/2. I dont have the template for this, but both of them are fractions. I really don't have a clue as to what is radical notation. Please help me because I don't know what first step to take.

Use radical notation to rewrite the expression and then simplify, if possible: (49/25)^3/2.
:
The radical here means the square root symbol; sqrt%28n%29
:
You can write the square root using exponents too. n^(1/2) means exactly the same thing.
In this expression: %2849%2F25%29%5E%283%2F2%29 can be written %28sqrt%2849%2F25%29%29%5E3 using a radical
:
you can factor inside the radical: %28sqrt%28%287%2A7%29%2F%285%2A5%29%29%29%5E3 to reveal perfect squares
extract the square roots, this gets rid of the radical and you have
%287%2F5%29%5E3 = %287%5E3%29%2F%285%5E3%29 = 343%2F125
