  1. What is the value of 5^3 × 5^2?

    Answer: 5^5

    When multiplying powers with the same base, add the exponents: 3 + 2 = 5.

  2. Which number is irrational?

    Answer: √2

    √2 cannot be written as a fraction and has a non-repeating, non-terminating decimal.

  3. A line passes through (0, 3) and has a slope of 2. What is its equation?

    Answer: y = 2x + 3

    Slope-intercept form y = mx + b gives slope 2 and y-intercept 3.

  4. Solve for x: 3x - 7 = 11.

    Answer: 6

    Add 7 to both sides to get 3x = 18, then divide by 3 to get x = 6.

  5. What is the approximate value of √50 to the nearest whole number?

    Answer: 7

    √49 = 7 and √50 is just slightly more, so it rounds to 7.

  6. Express 0.0045 in scientific notation.

    Answer: 4.5 × 10^-3

    Move the decimal three places right to get 4.5, so the exponent is -3.

  7. If a function pairs each input with exactly one output, the relation is called a what?

    Answer: Function

    A function assigns exactly one output to each input.
