Question

determine a metade do quadrado de um terço

Answer 1

         N = 1/3
         quadrado
                = N^2 = (1/3)^2
         metade
                = [(1/3)^2]/2
                = (1/9)/2
                                          = 1/18   RESULTADO FINAL

Answer 2

$\frac{( \frac{1}{3})^{2} }{2}= \frac{ \frac{1}{9} }{2} = \frac{1}{9}.\frac{1}{2} = \frac{1}{18}$
