solve exponential equations

Solve: 7^-x = 49

• x = 1
• x = -1
• x = 2
• x = -2

Sovle for x:
5^{-3x - 1} = 25

• x = -1
• x = -4
• x = -3
• x = 1

Solve 3³ = 3^{4x + 2}

• x = ¼
• x = -¼
• x = ½
• x = -½

Solve 8 = 2^5x+7

• x = ⅘
• x = ¼
• x = -⅘
• x = -¼

8^3x+3 = 8⁶

• x=28
• x=3
• x=1
• x=12

Solve the equation for x.

• x = 2
• x = 3
• x = 8
• x = 64

Solve for n:
