Solving Exponential Equations by Using Logarithms

Solve the exponential equation:

• -11/4

• 6

• 9/4

• 8

Solve for x: 32^x+1=8^x-3

• x=2

• x=4

• x=5

• x=-1

Solve for x: 5^x=1/125

• x=-3

• x=4

• x=1/3

• x=1

Solve 243^-3x-2 = 27^2-2x

• -9/10

• -16/9

• 8

• 0

• 2

• -2

• 1

• -1

• -3/7

• -2

• 3/7

• No solution

Solve for x:
12^2x-10 = 1

• 1

• 10

• -5

• 5

10^2x+4 =100000

• x=7

• x=20

• x=-1/2

• x=1/2

• Divide both sides by 3

• Divide both sides by e

• Take the natural log of both sides

• Rewrite the exponent 0.08t as the coefficient of "e"

• Subtract e to both sides

To solve 24000 = 12000e^0.03t , what would the next step be?
