Compute 4^3 * 4^5.

Compute 4^3 * 4^5.

• A. 4^7
• B. 4^9
• C. 4^8
• D. 4^6

Answer: (C)

When you multiply powers with the same base, you add the exponents. For 4^3 * 4^5, the exponents 3 and 5 add to 8, so the product is 4^8. If you want a quick check, 4^8 equals 65536, which matches the result. The other possible values would come from adding different exponents, not the numbers given here, so they don’t fit the expression.
