Question

simplify. express your answer using positive exponents.
$8pq^{7}r^{8} \cdot 7pqr$

Explanation:

Step1: Multiply coefficients

$8 \times 7 = 56$

Step2: Combine p terms

$p^1 \times p^1 = p^{1+1} = p^2$

Step3: Combine q terms

$q^7 \times q^1 = q^{7+1} = q^8$

Step4: Combine r terms

$r^8 \times r^1 = r^{8+1} = r^9$

Step5: Combine all parts

$56p^2q^8r^9$

Answer:

$56p^2q^8r^9$
