Logs and Exponential Equations

Solve: 2^x = 4^x+1

• x = -2

• x = 2

• x = -3

• x = 3

Solve for p:
4^p+2 = 64

• p = -16/9

• p = 1

• p = 8

• p = 7/6

Solve for x:
3^2x = 27^{x - 4}

• x = 12

• x = 4

• x = -4

• x = 1

Solve: 7^-x = 49

• x = 1

• x = -1

• x = 2

• x = -2

Write 7² = 49 in logarithmic form.

• log₇(7) = 2

• log₇(49) = 7

• log₇(49) = 2

• log₇(14) = 2
