Precalculus Properties of Logarithmic Functions Natural Logs 1 Answer Shwetank Mauria Sep 19, 2016 x=-5 Explanation: (125^(2x+1))/(625^(x+2))=3125^(x+2) or ((5^3)^(2x+1))/((5^4)^(x+2))=(5^5)^(x+2) or (5^(3xx(2x+1)))/(5^(4xx(x+2)))=5^(5xx(x+2)^ or (5^(6x+3))/(5^(4x+8))=5^(5x+10) or 5^(6x+3-4x-8)=5^(5x+10) or 5^(2x-5)=5^(5x+10) or 2x-5=5x+10 or 2x-5x=10+5 or -3x=15 or x=15/-3=-5 Answer link Related questions What is the natural log of e?
