Answer 1

Răspuns:

$a) 6 \times ( - 3) + 15 - {8}^{2} = - 18 + 15 - 64 = - 3 - 64 = - 67 \\ b)12 \div ( - 3) - 6 + {( - 10)}^{3} = - 4 - 6 - 1000 = - 10 - 1000 = - 1010 \\ c) {( - 5)}^{5} \times (6 - 2 \times ( - 18)) = - 3125 \times (6 + 36) = - 3125 \times 42 = 131250 \\ d)(6 - (4 \times (( - 2) - 10))) + {8}^{2} = (6 - (4 \times ( - 2 - 10))) + 64 = (6 - (4 \times ( - 12))) + 64 = (6 - ( - 48)) + 64 = (6 + 48) + 64 = 54 + 64 = 118$
