Pre-Calculus Logarithms

Rewrite the equation into logarithmic form:
6² = 36

• log₆ 2 = 36

• log₆ 36 = 2

• ln 36 = 2

• 6³⁶ = 2

Expand

• 5log₅a - 6log₅b

• 5log₅a - 30log₅b

• 5log₅a + 30log₅b

• 30log₅b - 5log₅a 

Solve for x

• x = 8

• x = 4

• x = 256

• x = 32

log₂(¹/₈) = -3

• 2^-3 = ¹/₈

• 2^1/8 = -3

• -3² = ¹/₈

• -3^1/8 = 2
