Find the first four terms of the indicated expansions
\n" ); document.write( "( 2x^2 + y/3) ^15
\n" ); document.write( "---------
\n" ); document.write( "= 15C15(2x^2)^15+15C14(2x^2)^14(y/3)+15C13(2x^2)^13(y/3)^2+15C12(2x^2)^12(y/3)^3
\n" ); document.write( "-----------------
\n" ); document.write( "= 32768x^30 + 15*16384/3*x^28y + 105*8192/9*x^26y^2 + 455*4096/27*x^24y^3
\n" ); document.write( "-----
\n" ); document.write( "= 32768x^30 + 81920x^2y + 95573.33x^26y^2 + 60025.19x^2y^3
