1.  {{{ (2x^2y^1z^2)*(x^2y^2z^2)^3}}}


When you raise a power to a power, you multiply the exponents.  This should give you:
{{{(2x^2y^1z^2)*(x^6y^6z^6)}}}


Now, when you multiply with the same base number you add exponents:
{{{2 *x^8* y^7* z^8 }}}


2. {{{(f/3)^3 }}} = {{{(f^3)/(3^3)}}} = {{{(f^3)/27}}}



3. {{{(3/5)^ -2}}}


The negative exponent means to take the reciprocal of the fraction:
{{{(3/5)^ -2}}}
{{{(5/3)^ 2}}}


Now, just square the numerator and square the denominator.

{{{25/9}}}
