Explanation of Solution

Given information:

Simplify the expression.

  (9x3yy3)1/2

Calculation:

For a real number x&y and rational numbers n&m use following exponent properties.

  a)xmxn=xm+nb)(xm)n=xmnc)xn=1xnd)(xy)n=xnyn

Now consider,

  (9x3yy3)1/2=(9x3y1(3))1/2=91/2x3/2y4/2=3x3/2y2

Hence, the simplified expression is, 3x3/2y2
