x amount of 5730 years has passed
\n" ); document.write( "there was originally y amount of carbon-14
\n" ); document.write( "now, there is 0.59y left of the carbon-14
\n" ); document.write( "0.59y = y(0.5)^(x)
\n" ); document.write( "0.59 = (0.5)^x
\n" ); document.write( "log(0.59) = x * log(0.5)
\n" ); document.write( "log(0.59) / log(0.5) = x
\n" ); document.write( "x = about 0.76 amount of 5730 years
\n" ); document.write( "Product = 4,361.75 years about \n" ); document.write( "
