vreau si eu rezolvarea la subpunctele a, e si j!
mulțumesc! ​

Answer 1

$a) \: \: \sqrt{ {( - 2)}^{6} \times {( - 3)}^{2} \times {( - 5)}^{2} } \\ \sqrt{64 \times 9 \times 25} \\ \sqrt{64} \times \sqrt{9} \times \sqrt{25} \\ 8 \times 3 \times 5 \\ 24 \times 5 = 120$

$e) \: \: \sqrt{ {( - 2)}^{4} \times {( - 14)}^{2} \times {( - 15)}^{2} } \\ \sqrt{16 \times 196 \times 225} \\ \sqrt{16} \times \sqrt{196} \times \sqrt{225} \\ 4 \times 14 \times 15 \\ 56 \times 15 = 840$

$i) \: \: \sqrt{ {( - 2)}^{8} \times {( - 3)}^{2} \times {5}^{2} } \\ \sqrt{256 \times 9 \times 25} \\ \sqrt{256} \times \sqrt{9} \times \sqrt{25} \\ 16 \times 3 \times 5 \\ 48 \times 5 = 240$
