You can put this solution on YOUR website!
(P - Q)^3
\n" ); document.write( "(18 - 21)^3
\n" ); document.write( "(-3)^3
\n" ); document.write( "= -27
\n" ); document.write( "R^3
\n" ); document.write( "= -6^3
\n" ); document.write( "= -216
\n" ); document.write( "S^2
\n" ); document.write( "-4^2
\n" ); document.write( "= 16
\n" ); document.write( "(P-Q)power3/R power3+Spower2
\n" ); document.write( "-27/-216 + 16
\n" ); document.write( "Common Denominator -216
\n" ); document.write( "(-27 + -3456)/-216
\n" ); document.write( "= 16.125
\n" ); document.write( "Hope this helps.
