ALGEBRA
Evaluate the given expressions (to two decimal places). (a) ) log((23.0) (b) ) log_(2) \(128\) (c) ) log_(9) \(1\)

ALGEBRA
Use the definition of logarithm to simplify each expression. (a) )log_(3b) \(3b\) ((b) )log_(8b) \((8b)^6\) (c) )log_(10b) \((10b)^(-13)\)

ALGEBRA
(a) Write the expression in terms of natural logarithms. (Express all logarithmic functions in terms of ln(x) in your answer.) log_(8.5) \(127\) = Give a calculator approximation (correct to four decimal places). log_(8.5) \(127\) ~=

ALGEBRA
Select all statements that are true. (log_b\(A\))/(log_b\(B\))=log_b\(A-B\) (If ) log_1.5\(8\)=x, text( then ) x**(1.5) =8. log\(500\) text( is the exponent on ) 10 text( that gives ) 500. text (In )log_b\(N\), text( the exponent is )N. text( If ) 2log_3\(81\)=8, text( then ) ...

ALGEBRA
Find a simplified value for x by inspection. Do not use a calculator. (a) log5(25) = x (b) log2(16) = x

ALGEBRA
Contract the expressions. That is, use the properties of logarithms to write each expression as a single logarithm with a coefficient of 1. text ((a) ) ln\(3\)-2ln\(4\)+ln\(8\) ((b) ln\(3\)-2ln\(4+8\) (c) )ln\(3\)-2(ln\(4\)+ln\(8\))

ALGEBRA
Solve the equations by finding the exact solution. ln\(x\) - ln\(9\) = 3

ALGEBRA
Solve the equations by finding the exact solution. (a) 1 = x - 1 (B)

ALGEBRA
ln\(e\) = ln\( sqrt(2)/x \) -ln\(e\)
