Question 886469

Simplify each expression. Assume that all variables represent positive numbers.

{sqrt(sqrt(y^3z))} 
the problem is the square root of the square root of y^3z.

how is this simplified?
Thanks for the help!
<pre>
{{{sqrt(sqrt(y^3z))}}}
{{{sqrt((y^3z)^(1/2))}}}
{{{sqrt((y^3)^(1/2)*z^(1/2))}}}
{{{sqrt(y^(3/2)* z^(1/2))}}}
{{{(y^(3/2) * z^(1/2))^(1/2)}}}____{{{highlight(highlight(y^((3/2)(1/2)) * z^((1/2)(1/2))))}}}____{{{highlight_green(highlight_green(y^(3/4)z^(1/4))))}}}
You can do the check!!
