Write 121 raised to the one-half power equals 11 as a logarithmic function

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.
