  1. What is the value of 2^5 · 2^3?

    Answer: 2^8

    When multiplying powers with the same base, add the exponents: 5 + 3 = 8.

  2. Simplify (3^4) / (3^2).

    Answer: 3^2

    When dividing powers with the same base, subtract the exponents: 4 − 2 = 2.

  3. What is (5^2)^3?

    Answer: 5^6

    A power raised to a power multiplies the exponents: 2 × 3 = 6.

  4. Evaluate 7^0.

    Answer: 1

    Any nonzero base raised to the zero power equals 1.

  5. What is the value of 4^(-2)?
