log 81^x=1/4
\n" ); document.write( "----
\n" ); document.write( "base = 10
\n" ); document.write( "exponent = 1/4
\n" ); document.write( "result = 81^x
\n" ); document.write( "----
\n" ); document.write( "Write in exponential form:
\n" ); document.write( "10^(1/4) = 81^x
\n" ); document.write( "---
\n" ); document.write( "81^x = 1.7783
\n" ); document.write( "---
\n" ); document.write( "Take the log of both sides to get:
\n" ); document.write( "x*log(81) = log(1.7783)
\n" ); document.write( "---
\n" ); document.write( "x = log(1.7783)/log(81)
\n" ); document.write( "x = 0.1310
