Basic Logarithmic Evaluation

Rewrite as a log: x = 11^y

• log₁₁(y) = x

• log_y(11) = x

• log₁₁(x) = y

• log_x(y) = 11

Find x: log₅(x) = 4

• x = 20

• x = 25

• x = 625

• x = 125

Find x: log₅(x) = 0

• No Solution

• x = 0

• x = 5

• x = 1

Convert log(x)=y+2 to exponential form.

• 10^(y+2)=x

• 1^x=y+2

• 10^x=y+2

• x^(y+2)=10

log₂32 = 5

• 2^-5 = 32

• 2³² = 5

• 32⁵ = 2

Convert 6^(x+2)=216 to logarithmic form

• log₂₁₆(x+2)=6

• log₆(x+2)=216

• log₆(216)=x+2

• log_(x+2)(216)=6
