WebLogᵦ (c) = a Where ᵦ is the base can be rewritten as. ᵦ^a = c That is ᵦ rasied to the power of a = c. Your expression is. log (3x+2)=2 and the base ᵦ is not shown. When log is used without the base shown, a base 10 is implied, So your equation is. log (base10) of (3x+2) = 2. You need to convert to the exponential form. Webx = 5 only Explanation: If the question just says log , we can safely assume that it means log10 log10x +log10(3x −13) = 1 ...

WebThis is a property of logs. For any number x, log_x (x) = 1. If we rewrite it in exponential form, you can more clearly see why this is true: x^1 = x. Now for your problem: ln (e^3) = 3 In this situation, we can take the exponent out and put it as a factor to multiply the log by. This gives … WebThen multiply through by log (3) to get log (x) = 2*log (3). Then use the multiplication property from the prior video to convert the right side to get log (x) = log (3^2). Then replace both sides with 10 raised to the power of each side again, to …
