7m^3n/8k^2 ÷ 21m^2n/4k

[tex] \frac{7m ^{3}n }{8k ^{2} } \div \frac{21m ^{2} n}{4k} \\ = \frac{7m ^{3} n}{8k ^{2} } \times \frac{4k}{21m ^{2} n} \\ = \frac{m ^{3 - 2} n ^{1 - 1} }{2k ^{2 - 1} } \times \frac{1}{3} \\ = \frac{m}{2k} \times \frac{1}{3} \\ = \frac{m}{6k} [/tex]
Maaf Kalau Salah

7m^3n/8k^2 : 21m^2n/4k
= 7m^3n/8k^2 × 4k/21m^2n
= m^3-2n^1-1/2k^2-1 × 1/3
= m/2k × 1/3
= m/6k
