What does the b in log_bA=x represent?

• Argument
• Base
• Exponent
• Bottom

Rewrite log_pt = m in exponential form.

• p^t = m
• t^m = p
• m^t = p
• p^m = t

Write in logarithmic form.
2^-4 = ¹/₁₆

• log₂(¹/₁₆) = -4
• log_-4(¹/₁₆) = 2
• log _-4 2 = ¹/₁₆
• log₂(-4) = ¹/₁₆

Rewrite the exponential equation into its logarithmic equation; x⁶=64

• log₆x=64
• log6=64
• log₆64=x
• log_x64=6

Solve for x
5^x = 17

• x = log₁₇5
• x = log 5 + log 17
• x = log₅17
• x = (log 5)/(log 17)
