Question 83296
<pre><font size = 4><B>
{{{(n^4m^7)^4(n^2p^3)^6}}}

To remove the parentheses:
Multiply each exponent inside a parentheses
by the exponent just outside that parentheses:

{{{n^(4*4)m^(7*4)n^(2*6)p^(3*6)}}}

{{{n^16m^28n^12p^18}}}

Add the exponents of n {{{16+12=28}}}

{{{n^28m^28p^18}}}
