Answer 1

Explicație pas cu pas:

a)

${5}^{3} \times {1111}^{3} - {5555}^{3} = \\ ( {5 \times 1111)}^{3} - {5555}^{3} \\ = {5555}^{3} - {5555}^{3} = 0$

b)

$( { {3}^{2} })^{5} - {3}^{10} + ( { {2}^{3}) }^{4} - {2}^{12} = \\ {3}^{10} - {3}^{10} + {2}^{12} - {2}^{12} = \\ 0 + 0 = 0$

c)

${2}^{7} \div ( { {2}^{2}) }^{3} + {3}^{3} \times {3}^{3} \div {3}^{5} + (3 \times 16 - 16) = \\ {2}^{7} \div {2}^{6} + {3}^{6} \div {3}^{5} + (48 - 16) = \\ {2}^{1} + {3}^{1} + 32 = 2 + 3 + 32 = 37$
