You can put this solution on YOUR website!
Solve for x in terms of k
\n" ); document.write( "log{subscript 5}x + log{subscript 5)(x+2) = k
\n" ); document.write( "x= ?
\n" ); document.write( "Find x if k=8 ?
\n" ); document.write( "------------------------
\n" ); document.write( "log5(x) + log5(x+2) = k
\n" ); document.write( "Rewrite:
\n" ); document.write( "log4[x(x+2)] k
\n" ); document.write( "x^2+2x = 4^k
\n" ); document.write( "--------------------
\n" ); document.write( "Now, if k = 8 you get:
\n" ); document.write( "x^2 + 2x = 4^8
\n" ); document.write( "---
\n" ); document.write( "x^2+2x- 65536 = 0
\n" ); document.write( "Comment:
\n" ); document.write( "This does not factor neatly.
\n" ); document.write( "It can be solved using the quadratic formula.
\n" ); document.write( "I'll leave that to you.
\n" ); document.write( "Cheers,
