To remove the parentheses, 

1. Make sure every factor has an exponent.
So we give 3 and 5 an exponent of 1



2. multiply every exponent inside the parentheses 
by the exponent just outside the paretheses and
remove the parentheses:



We get all the exponents positive by moving every
factor with a negative exponent from the bottom
to the top or from the top to the bottom. Leave
the factors with positive exponents where they 
are:



Add exponents of factors with the same base.
Write 54 as 125 and 34 as 81.
