Alg 2 02 Unit 7a Test A: Exponential and Logarithms Functions

Which functions represent exponential growth? Check all that apply.

Which is equivalent to

5^{x}=32

Which is equivalent to log_{3}18=x+2

The expression log_{25}5 is equivalent to which of the following

Solve for x:

9^{3x-7}=9^{5-x}

Solve for x

\frac{1}{27} =3^{4m-1}

Slove for n:

4^{3}\cdot4^{2n-9}=64

Solve: log 1000

Solve log_{3}92 (put your answer to 3 decimal places)

Which is equivalent to log(\frac{b^3}{a})

Which is equivalent to the expression:

2log x-2(log y+log y)

Simplify the expression below

log_{2}2+log_{3}27

Simplify (condense) 3log_4{8} - 5log_{4}2 (your answer should have a log)

OPTIONAL: Condense, then use the change of base formula to evaluate the logarithm (your answer should be a number to 4 decimal places)

log_{2}27+log_{2}4-2\cdot log_{2}3

OPTIONAL: Expand the expression (HINT: your answer should have a minus sign and no exponents)

log(\frac{x^9}{y^4})

OPTIONAL Expand
