Exam 6 Review (Unit 10 - Exponents, Logarithms s and e)

Rewrite as an exponential: log₂8 = 3

• 3² = 8

• 2³ = 8

• 2⁸ = 3

• 8³ = 2

• x = -1

• x = 1

• x = 0

• No Solution

Find x: log_x(25) = 2

• x = 1

• x = 12.5

• No Solution

• x = 5

Rewrite as a log: x = 11^y

• log₁₁(y) = x

• log_y(11) = x

• log₁₁(x) = y

• log_x(y) = 11

What is the range?

• (-∞, ∞)
• (0, ∞)
• [1, ∞)
• (1, ∞)
