use the properties of exponents to simplify the expression

4. anonymous

$(=3^3m^{\frac{3}{2}}n^{-6})^{\frac{2}{3}}$Take the cube root of each factor inside the parentheses (divide each exponent by 3)$=(3m^{\frac{1}{2}}n^{-2})^{2}$then, square each factor (multiply each exponent by 2)$=3^2mn^{-4}$$=9mn^{-4}$
