66 pq^2 r ^ 3 \div 11 q r ^2

Answers (1)

We have,
               66pq^2r^3 = 2 \times 3 \times 11 \times p \times q \times q \times r \times r \times r
              11qr^2 = 11 \times q \times r \times r
Therefore,
                    \frac{66pq^{2}r^{3}}{11qr^{2}} = \frac{2 \times 3 \times 11 \times p \times q \times q \times r \times r \times r}{11 \times q \times r \times r} = 6pqr
