1 y dy dx = 1 dy dx = y = ex. 3. y = √ x2 +1 Solution. y = p x2 +1 =⇒ lny = 1 2 ln(x2 +1) 1 y dy dx = 1 2 2x x2 +1 dy dx = xy x2 +1 = x √ x2 +1 x2 +1 = x √ x2 +1. Again, notice this is the same answer we could have gotten without logarith-mic differentiation. 4. y = xsinx Solution. lny = lnx+ln(sinx) 1 y dy dx = 1 x + cosx sinx dy dx ...

6. We use the definition of the quantity log b a as being the number which you must raise b to in order to get a (when a>0).In other words, blogb a = a by definition. So, log 5 125 = 3 since 5 3 = 125,log 4 1 2 = −1 2 since 4−1/2 = 1 2, log1000000 = 6 since 106 = 1000000, log b 1 = 0 since b0 =1,ln(ex)=x since ex = ex (ln(a) means log base-e of a, where e ≈ 2.718). 7. To simplify the ...

In Example 1, the Properties of Logarithms were only used to combine logarithms in each problem. This is how we will be using the Properties of Logarithms in this class, to combine logarithms in order to reduce the number logarithms we have to just one, so that we can then convert that one logarithm to exponential form to solve.
