• Argument

• Base

• Exponent

• Bottom

Multiple Choice

How do you properly read log₁₀100=2?

• log base 10 of 100 is equal to 2

• log base of 10 is equal to 2

• log 100 of 10 is equal to 2

• log of 100

Multiple Choice

Rewrite log_pt = m in exponential form.

• p^t = m

• t^m = p

• m^t = p

• p^m = t

 $\log_pt=m$  

 $p^m=t$  

Multiple Choice

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

• log₆x=64

• log6=64

• log₆64=x

• log_x64=6

 $x^6=64$  

 $\log_x64=6$  

Multiple Choice

Rewrite log_vn = a in exponential form.

• v^a = n

• n^a = v

• vⁿ = a

• aⁿ = v

Multiple Choice

Write in exponential form:

log ₂ 32 = 5

• 2⁵ = 32

• 5² = 32

• 5³² = 2

• 2³² = 5

 $\log_ba=e$  

 $b^e=a$
