Answer 1

$\sqrt{ {( - 2)}^{6} \times {( - 3)}^{4} \times {5}^{2} } - \sqrt{ {2}^{2} \times {( - 3)}^{2} \times {( - 5)}^{2} }$

$= \sqrt{64 \times 81 \times 25} - \sqrt{4 \times 9 \times 25}$

$= \sqrt{64} \times \sqrt{81} \times \sqrt{25} - \sqrt{4} \times \sqrt{9} \times \sqrt{25}$

$= 8 \times 9 \times 5 - 2 \times 3 \times 5$

$= 72 \times 5 - 6 \times 5$

$= 5 \times (72 - 6)$

$= 5 \times 66$

$= 330$
