  1. 3
  2. 6
  3. 9

The index laws give 3^(4 - 1 - 1) = 3^2 = 9.

2. What is the value of log base 10 of 0.001?
  1. -3
  2. -2
  3. 2
  4. 3

Answer: A. -3

Since 0.001 = 10^-3, its common logarithm is -3.

3. Simplify sqrt(50) - sqrt(8).
  1. 7sqrt(2)
  2. sqrt(42)
  3. 2sqrt(2)
  4. 3sqrt(2)

Answer: D. 3sqrt(2)

sqrt(50) - sqrt(8) = 5sqrt(2) - 2sqrt(2) = 3sqrt(2).

4. In a class of 30 students, 18 study French, 14 study Hausa and 6 study both; how many study neither language?
  1. 2
