2b SQRT^3(16b^2) + SQRT^3(128b^5)
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "Do you mean 2b(cube root of 16b^2) + (cube root of 128b^5)
\n" ); document.write( "-----
\n" ); document.write( "If so you get:
\n" ); document.write( "2b(2*cbrt(2b^2)) + 4b*cbrt(2b^2)
\n" ); document.write( "---
\n" ); document.write( "(4b + 4b)*cbrt(2b^2)
\n" ); document.write( "---
\n" ); document.write( "8b*cbrt(2b^2)
\n" ); document.write( "==========================
