If x = 4, then x4 ÷ x = ____________.

  1. 12
  2. 36
  3. 64
  4. 72

Answer(s): C

Explanation:

Substitute 4 for all x’s in the problem. 44 ÷ 4 = (4 × 4 × 4 × 4) ÷ 4 = 256 ÷ 4 = 64.



Solve for x: 5 − 3x ≥ 14 + 6x

  1. x ≥ −1
  2. x ≤ −1
  3. x > −1
  4. x < −1

Answer(s): B

Explanation:

5 − 3x ≥ 14 + 6x
5 − 3x – 6x ≥ 14
−9x ≥ 14 − 5
−9x ≥ 9
x ≤ −1



(900 × 3) ÷ 6 = _______________.

  1. 45
  2. 450
  3. 55
  4. 550

Answer(s): B

Explanation:

(900 × 3) ÷ 6 = 2,700 ÷ 6 = 450



If x = 2, then xx × xx = ______________.

  1. 16
  2. 2xx
  3. 8
  4. 24

Answer(s): A

Explanation:

Substitute 2 for all the x’s. xx × xx= (2 × 2) × (2 × 2) = 4 × 4 = 16



Solve for x: x2 − 2x − 15 = 0

  1. 4, −2
  2. 3, −3
  3. 5, −3
  4. −1, 1

Answer(s): C

Explanation:

This is a quadratic equation that can be solved by factoring and setting each factor equal to zero.
x2 − 2x − 15 = 0 (x − 5)(x + 3) = 0 x − 5 = 0x + 3 = 0 x = 5x = −3
