**Henry**, Wednesday, May 22, 2013 at 8:13pm51. X^3/0.3^-3 = 125

0.3^3X^3 = 125

X^3 = 125/0.3^3

X^3 = 5^3/0.3^3

X = 5/0.3

X = 16.66666667.

67. e^3x = 8

3xLne = Ln8

3x*1 = Ln8

X = Ln8/3.

68. 1/e^x = 7

e^x = 1/7

x*Ln e = Ln 1/7

x*1 = Ln 1/7

X = Ln 1/7.

69. 3e2x+2 = 50

6ex = 48

X = 48/6e = 8/e = 2.943

70. |Ln x| = 1

Ln x = 1

X = e^1 = e = 2.7182.

78. Increase = 96000-80,000 = $16,000

%Increase = (16000/80000)*100%=20%/yr.

V = 80000(1+0.2)^3 = $138,240.
