What is the solution(s) to log base 4 of 4x + log base 4 of (x+3) = 2 \n" ); document.write( "log4[(4x)(x+3)]=2 \n" ); document.write( "convert to exponential form: base(4) raised to log of number(2)=number(4x)(x+3) \n" ); document.write( "4^2=(4x)(x+3)=16 \n" ); document.write( "4x^2+12x=16 \n" ); document.write( "4x^2+12x-16=0 \n" ); document.write( "x^2+3x-4=0 \n" ); document.write( "(x+4)(x-1)-0 \n" ); document.write( "x=-4 (reject,x>0) \n" ); document.write( "or x=1 \n" ); document.write( " |
