Question

simplify. express your answer using positive exponents. (3k^8)(7k^2)

Explanation:

Step1: Multiply the coefficients

$3 \times 7 = 21$

Step2: Combine like variable terms

When multiplying terms with the same base, add exponents: $k^8 \times k^2 = k^{8+2} = k^{10}$

Step3: Combine results

Multiply the coefficient result with the variable result.

Answer:

$21k^{10}$
