Exponential vs. Logarithmic Functions

Rewrite the following exponential form into its logarithmic form:

M^K = X

• Log_M X = K

• Log_X K = M

• Log_K X = M

• Log_K M = X

Rewrite the logarithmic function into its expoential form:

Log_S F = T

• S^T = F

• T^F = S

• F^T = S

• S^F = T

Finish the formula:

Log R^V = _________

• V Log R

• R Log V

• Log R - Log V

• Log V - Log R

Finish the formula:

Log RV = _________

• Log R + Log V

• Log R - Log V

• V Log R

• R Log V

Finish the formula:

Log (R/V) = _________

• Log R - Log V

• Log R + Long V

• R Log V

• V Log R
