The number bacteria growing in an incubation culture increases with time according to B(x)=8,200(5)^x, where x is time in days. After how many days will the number of bacteria in the culture be 205,000?
\n" ); document.write( "

\n" );
document.write( "\"B%28x%29+=+8200%285%5Ex%29\"
\n" );
document.write( "\"205000+=+8200%285%5Ex%29\" ------ Substituting 205,000 for B(x)
\n" );
document.write( "\"205000%2F8200+=+5%5Ex\"
\n" );
document.write( "\"25+=+5%5Ex\"
\n" );
document.write( "\"5%5E2+=+5%5Ex\"
\n" );
document.write( "2 = x ------ Bases are equal, and so are the exponents
