8x^(2/3) − 200 = 0
\n" ); document.write( "---
\n" ); document.write( "x^(2/3) = 25
\n" ); document.write( "---
\n" ); document.write( "x = 25^(3/2)
\n" ); document.write( "---
\n" ); document.write( "x = 5^3
\n" ); document.write( "x = 125

\n" ); document.write( "Solve the equation for the indicated variable.
\n" ); document.write( "V = (1/3)πr2h ; for r
\n" ); document.write( "---
\n" ); document.write( "(pi)r^2h = 3V
\n" ); document.write( "----
\n" ); document.write( "r^2 = (3V)/[(pi)h]
