If a = x^5 and b + 2y^3 express the following in terms of x and y
\n" ); document.write( "Substitute for \"a\" and for \"b\"::
\n" ); document.write( "a) 4a^2b^3 = 4(x^5)^2*(2y^3)^3
\n" ); document.write( "----
\n" ); document.write( "= 4*x^10*8y^9)
\n" ); document.write( "= 32x^10y^9
\n" ); document.write( "=============================
\n" ); document.write( "b) (12a^5b^8) / (6a^3b^2)
\n" ); document.write( "1st: Simplify the fraction to get::
\n" ); document.write( "= (12/6)(a^5/a^3)(b^8/b^2)
\n" ); document.write( "-------
\n" ); document.write( "= 2a^2b^6
\n" ); document.write( "-------
\n" ); document.write( "2nd: Substitute or \"a\" and for \"b\"::
\n" ); document.write( "= 2(x^5)^2*(2y^3)^6
\n" ); document.write( "= 2x^10*64y^18
\n" ); document.write( "---
\n" ); document.write( "= 128x^10y^18
\n" ); document.write( "=====================
