Introduction to Logarithms and Exponential

Log with a base "e" (log_e) is the same thing as...

• e

• Natural Logarithm (LN)

• Common Logarithm (Log)

• Natural Log, base "e"
  LN_e

Rewrite in exponential form.

• A

• B

• C

• D

Rewrite the equation in logarithmic form.

• A

• B

• C

• D

• x = 2

• x = -2

• y = 2

• y = -2

Find the inverse of y=9^x

• y=log_x9

• y=log₁₀9

• x=log_y9

• y=log₉x

How are exponentials and logarithms related?

• They're cousins

• They're inverses

• They're not related

• They're reciprocals

Rewrite 3⁴ = 81 in logarithmic form.

• log₃4 = 81

• log₈₁3 = 4

• log₃81 = 4

• log₄81 = 3

Rewrite log_pt = m in exponential form.

• p^t = m

• t^m = p

• m^t = p

• p^m = t

Evaluate log_b(1)

• 0

• 1

• -1

• b
