Question

simplify. express your answer using positive exponents. (5jk^7)(2j^4k^3)

Explanation:

Step1: Multiply the coefficients

$5 \times 2 = 10$

Step2: Combine $j$ terms (add exponents)

$j^1 \times j^4 = j^{1+4} = j^5$

Step3: Combine $k$ terms (add exponents)

$k^7 \times k^3 = k^{7+3} = k^{10}$

Step4: Multiply all simplified parts

$10 \times j^5 \times k^{10}$

Answer:

$10j^5k^{10}$
