Logarithmic Expressions

Logarithmic functions are the inverse of...

• Linear Functions

• Exponential Functions 

• Quadratic Functions 

• Polynomial Functions 

Write log₆ 216 = 3 in exponential form.

• 3⁶=216

• 6³=216

• 216⁶=3

• 3²¹⁶=6

Write log₂ 0.25 = -2 in exponential form

• -2²  = 0.25

• -2^0.25  = 2

• 2^-2  = 0.25

• No correct answer

In the expression log 25, the base of the log is equal to

• 10

• 1

• e

• 2

Rewrite the equation into logarithmic form:

6² = 36

• log₆ 2 = 36

• log₆ 36 = 2

• ln 36 = 2

• 6³⁶ = 2

How are exponential and logarithmic functions related?

• Opposites

• Inverses

• Cousins

• Reciprocals

log₂32 = 5

• 2^-5 = 32

• 2³² = 5

• 2⁵ = 32

• 32⁵ = 2

What is the base when you convert to logarithmic form: 2^x=15
