Consider the expressions separately:

[tex] \frac{35}{25-5*4}= \frac{35}{25-20}=\frac{35}{5}=7[/tex]

[tex] \frac{225}{( 5*6-5 )( \frac{729}{81} )}= \frac{225}{( 30-5 )( 9 )}= \frac{225}{( 25 )( 9 )}= \frac{9}{9}=1[/tex]

So:[tex]\frac{35}{25-5*4}-\frac{225}{( 5*6-5 )( \frac{729}{81} )}=1-7=-6[/tex]
