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 … WebNotice that the numerator and the denominator on the RHS are both square numbers. Also notice that you see 5 on the LHS and 5² on the RHS. So maybe x=2. But (5/2) 2=25/4. The problem is that the numerator and denominator are the wrong way around. So raise both sides to the power of -1. That gives (5/2)-2=4/25, so x=-2. binaural cleansing class
