Answer 1

Explicație pas cu pas:

$a. \\ ( - {3})^{4} - ( - {4})^{0} + ( - {2})^{4} = \\ 81 - 1 + ( + 16) = \\ 81 - 1 + 16 = \\ 80 + 16 = 96 \\ \\ b. \\ ( - {3})^{3} + ( - {1})^{0} - ( - {2})^{2} + ( - {5})^{2} = \\ - 27 + 1 - 4 + 25 = \\ - 26 - 4 + 25 = \\ - 30 + 25 = - 5 \\ \\ c. \\ {4}^{3} \div ( - {2})^{3} + ( - {1})^{5} = \\ 64 \div( - 8) + ( - 1) = \\ - 8 - 1 = - 9 \\ \\ d. \\ ( {5}^{2} ) + ( - 5) {}^{2} + ( - {2}^{4} ) = \\ 25 + 25 + ( - 16) = \\ 50 - 16 = 34 \\ \\ e. \\ ( - {8}^{2} ) + ( - {4})^{2} - ( - {10})^{2} = \\ - 64 + 16 - 100 = \\ - 48 - 100 = - 148 \\ \\ f. \\ ( - {5})^{2} + ( - {12})^{2} - ( - {13})^{2} = \\ 25 + 144 - 169 = \\ 169 - 169 = 0$
