Express log 10 AB ( ) as the sum of two logarithms (of A and B ) n. Express ln A B ( ) as the difference of two logarithms o. Express log 10 A 2 ( ) in terms of A (without the term A 2 ) 2. Sketch (with axis labels) the following (by hand or with software such as MATLAB): a. W = x 2 b. X = 10 y c. Y = 10log 10 x ( ) (note that this is known as the Decibel (dB) scale, and we will say that Y is the quantity x expressed in dB)
