Mark as brainliest and follow...

${7}^{2} \times {7}^{3} \times {10}^{2} \times {10}^{ - 3} \times {3}^{ - 3} \times {7}^{ - 2}$

${7}^{(2 + 3 - 2)} \times {10}^{(2 - 3)} \times {3}^{ - 3}$

${7}^{3} \times {10}^{ - 1} \times {3}^{ - 3}$

$\frac{ {7}^{3} }{ {10}^{1} \times {3}^{3} }$

$\frac{343}{10 \times 27}$

$\frac{343}{270}$
