What is the value of (3^5 \times 3^2)?

Answer and explanation

Correct answer: 2187

When powers with the same base are multiplied, their exponents are added: \(a^m \times a^n=a^{m+n}\). Therefore, \(3^5 \times 3^2=3^{5+2}=3^7=2187\). The distractor 729 equals \(3^6\), which results from adding one exponent incorrectly. Exam tip: for multiplication of powers with the same base, add the exponents and keep the base unchanged.
