Applying and analysing exponential and logarithmic functions

Solve for x: log₂(8) = x

• 5

• 4

• 3

• 2

Solve for x:

log₄(64)=x.

• 16

• 10

• 3

• 8

Write in logarithmic form:
9² = 81

• log ₉ 81 = 2
• log ₂ 81 = 9
• log ₉ 2 = 81
• log ₂ 9 = 81

Rewrite the following equation in exponential form:
 $\log_381=4$  

•  $4^3=81$  

•  $3^4=81$  

•  $81^3=4$  

•  $4^{81}=3$  

Solve each equation. Select the closest answer.

• $\frac{\log\left(69\right)-2}{9}$

• $\frac{\log67}{9}$

• $\log\left(\frac{67}{9}\right)$
