2 = 1.07^t
\n" ); document.write( "---
\n" ); document.write( "take the log base 1.07 of both sides:
\n" ); document.write( "logBase(1.07)of(2) = logBase(1.07)of(1.07^t)
\n" ); document.write( "logBase(1.07)of(2) = t
\n" ); document.write( "---
\n" ); document.write( "use the Change-of-Base formula on the left side:
\n" ); document.write( "logBase(a)of(x) = logBase(10)of(x) / logBase(10)of(a)
\n" ); document.write( "---
\n" ); document.write( "logBase(1.07)of(2) = t
\n" ); document.write( "logBase(10)of(2) / logBase(10)of(1.07) = t
\n" ); document.write( "0.301029995664 / 0.0293837776852 = t
\n" ); document.write( "10.2447683511 = t
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "t = 10.2447683511
