Question

me ayudaaaa porfavor le doy coronitas​

Answer 1

$a) \sqrt{144} \times (20 - 3) + {7}^{10} \div {7}^{9} \\ = \sqrt{ {12}^{2} } \times 17 + {7}^{10 - 9} \\ = 12 \times 17 + {7}^{1} \\ = 204 + 7 \\ = 211 \\ \\ b)( \sqrt{16} + {9}^{2} \div {3}^{3} ) \times {54}^{0} - 7 \\ \\ = (\sqrt{ {4}^{2} } + 81 \div 27) \times 1 - 7 \\ = (4 + 3) \times 1 - 7 \\ = (7) \times 1 - 7 \\ = 7 - 7 \\ = 0 \\ \\ c) (\sqrt[3]{8} \times \sqrt[3]{27} )^{3} \times {4}^{3} \\ = ( \sqrt[3]{ {2}^{3} } \times \sqrt[3]{ {3}^{3} } )^{3} \times ( {2}^{2})^{3} \\ = (2 \times 3) ^{3} \times {2}^{6} \\ = {2}^{3} \times {2}^{6} \times {3}^{3} \\ = {2}^{3 + 6} \times {3}^{3} \\ = {2}^{9} \times {3}^{3} \\ = 512 \times 27 \\ = 13824$
