A=\frac{x^\frac{3}{2}×y^3}{z^\frac{1}{2}}
Take logarith on both sides.
logA=(3/2)logx+3logy-(1/2)logz
Take derivative.
\frac{dA}{A}=\frac{3}{2}\frac{dx}{x}+3\frac{dy}{y} -\frac{1}{2}\frac{dz}{z}
Relative error
 
|\frac{dA}{A}|=\frac{3}{2}|\frac{dx}{x}|+3|\frac{dy}{y} | + \frac{1}{2} |\frac{dz}{z}|
You can calculate its numerical value when relative errors in x,y,z are given.
Percentage error is
|dA/A|×100
Hope this helps.
Please approve if it does.
