Converting Exponential and Logarithmic

Rewrite 3⁴ = 81 in logarithmic form.

• log₃ 4 = 81

• log₈₁ 3 = 4

• log₃ 81 = 4

• log₄ 81 = 3

Change to Exponential Form:

log₆ 36 = 2

• 2⁶=36

• 6²=36

• 36²=6

• 36⁶=2

Rewrite the equation into logarithmic form:

6² = 36

• log₆ 2 = 36

• log₆ 36 = 2

• ln 36 = 2

• 6³⁶ = 2

Match each exponential expression to its equivalent logarithmic form.

• e^x ≈ 10

• log_x 3 = 10

• 10³ = x

• ln 10 ≈ x

• x¹⁰ = 3

• ln x ≈ 10

• 3^x = 10

• log₃ 10 = x

• e¹⁰ ≈ x

• log x = 3
