Q1. 0.0009 in scientific notation is:

  1. 9 × 10⁻⁴
  2. 9 × 10⁴
  3. 9 × 10⁻⁵
  4. 9 × 10⁻³
Show the answer

Answer: A. 9 × 10⁻⁴

Move the decimal point until one non-zero digit is before it: 0.0009 = 9 × 10⁻⁴.

Q2. The exponential form of log₅ 25 = 2 is:

  1. 5² = 25
  2. 5²⁵ = 2
  3. 25² = 5
  4. 2⁵ = 25
Show the answer

Answer: A. 5² = 25

The correct answer is “5² = 25”. log_b x = p ⇔ bᵖ = x, so 5² = 25.

Q3. A/an binary relation from A to B is:

  1. the set of all second elements of its ordered pairs
  2. the set of all first elements of its ordered pairs
  3. any subset of A × B
  4. a pair of elements (a, b) in which the order matters
Show the answer

Answer: C. any subset of A × B

Binary relation from A to B: any subset of A × B.

Q4. The LCM of 6x²y² and 14x³y² is:

  1. 2x²y²
  2. 84x³y²
  3. 42x²y²
  4. 42x³y²
Show the answer

Answer: D. 42x³y²

LCM: lowest common multiple of the numbers (42) and the highest power of each variable.

Q5. The sum of two consecutive integers is 45. The smaller integer is:

  1. 23
  2. 22
  3. 21
  4. 44
Show the answer

Answer: B. 22

The correct answer is “22”. x + (x + 1) = 45 ⇒ x = 22.

Q6. The y-intercept of the line 3x + 1y − 9 = 0 is:

  1. 3
  2. 10
  3. −9
  4. 9
Show the answer

Answer: D. 9

The correct answer is “9”. y-intercept = −c/b = 9.
