(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

Answer 1

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
