Unit 4 - Lesson 5 The Method of Common Bases

Solve for x using the same base method.
(-3)^x = (-3)¹³

• 13
• -3
• x + 13
• x -13

Solve for x using the same base method.
3^x-20 = 27

• 17
• 27
• -7
• 23

Solve: 9^8-x = 27^x-3

• x = 5

• x = -5

• x = 1/5

• x = -1/5

Solve for a:
5^{a + 2} = 1/125

• -1
• -6/7
• -5
• 4

Solve 3³ = (3²)^{2x + 1}

• x = ¼

• x = -¼

• x = ½

• x = -½
