What is the value of log16 4?

(the 16 is small and at the bottom of log)

4

1/2

1/4

2

Solve the exponential equation.

125^9x _ 2 = 150

_1.8847

_0.1069

0.3375

1.0378

Solve log (3x + 2) = 3.

1000/3

998/3

998

1/3

1) log (16) 4 = 1/2

Answer: B) 1/2

2) 125 ^ (9 x - 2) = 150

9 x - 2 = log (125) 150

9 x - 2 = 1.038

9 x = 1.038 + 2

9 x = 3.038

x = 3.038 : 9

x = 0.3375

Answer: C) 0.3375

3) log (3 x + 2) = 3

3 x + 2 = 10^3

3 x + 2 = 1000

3 x = 1000 - 2

3 x = 998

x = 998 / 3

Answer: B) 998 / 3
