Note that 625 = 5^4.
\n" ); document.write( "So the original equation 5^(x+7)=625^(x-7) becomes:
\n" ); document.write( "5^(x+7)=5^4(x-7)
\n" ); document.write( "Therefore x+7 = 4(x-7)
\n" ); document.write( "Solving the above equation for x, we have
\n" ); document.write( "x + 7 = 4x - 28
\n" ); document.write( "3x = 35
\n" ); document.write( "x = 35/3
\n" ); document.write( "
\n" ); document.write( "
