The use of calculators is allowed, but not necessary. There are 10 points possible. To receive partial credit on any problem work must be shown. 1. Simplify the following expression using the rules for logarithms. Ex- press your answer as a single logarithm 4 log( A ) + 2 log( B )- 4 log( C ) Soluitons. The computation follows as 4 log( A ) + 2 log( B )- 4 log( C ) = log( A 4 ) + log( B 2 )- log( C 4 ) = log( A 4 · B 2 )- log( C 4 ) = log A 4 · B 2 C 4 . 2. Expand the following expression using rules of logarithms and expo- nents. log √ m 2 n 5 p 6 ! Solutions. The computation follows as log √ m 2 n 5 p 6 ! = log m 2 / 2 · n 5 / 2 p 6 = log( m · n 5 / 2 )- log( p 6 ) = log( m ) + log( n 5 / 2 )- log( p 6 ) = log( m ) + 5 2 log( n )- 6 log( p ) Math 111I Sec 001 Group Quiz 6 Solutions 3.
