<PRE><B>Question 679231</B>
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(n)}}}
:
You can write the square root using exponents too.  n^(1/2) means exactly the same thing.

In this expression: {{{(49/25)^(3/2)}}} can be written {{{(sqrt(49/25))^3}}} using a radical
:
you can factor inside the radical: {{{(sqrt((7*7)/(5*5)))^3}}} to reveal perfect squares
extract the square roots, this gets rid of the radical and you have
{{{(7/5)^3}}} = {{{(7^3)/(5^3)}}} = {{{343/125}}}
