Unit 9 - Logs Review

Front

log(xy^2)

Back

logx + 2logy

Front

Rewrite 1.6^(x+2) = 14.1

Back

log_1.6 14.1 = x + 2

Front

log(4x)

Back

log4 + logx

Front

Use multiple log properties to write as a single log: log_2 x - 5log_2 y

Back

log_2 (x/y^5)

Front

Match the graph with its equation: y = log_4 (x) + 2, y = log_4 (x + 2) + 1, y = log_4 (x - 1) + 2, y = log_4 (-x + 2)

Back

y = log_4 (x + 2) + 1

Front

Definition of Logarithm

Back

The logarithm of a number is the exponent to which the base must be raised to produce that number.

Front

Change of Base Formula

Back

log_b a = log_k a / log_k b for any base k.

Front

Product Property of Logarithms

Back

log_b (xy) = log_b x + log_b y.

Front

Quotient Property of Logarithms

Back

log_b (x/y) = log_b x - log_b y.

Front

Power Property of Logarithms

Back

log_b (x^n) = n * log_b x.
