Réponse:
[tex]a = ( {10}^{23} \times {10}^{ - 4} ) \div {10}^{8} \\ = {10}^{23 + ( - 4)} \div {10}^{8} \\ = {10}^{23 - 4} \div {10}^{8} \\ = {10}^{19} \div {10}^{8} \\ = {10}^{19 - 8} \\ = {10}^{11} [/tex]
[tex]b = 3 \times {2}^{4} - {2}^{4} \\ = {2}^{4} (3 - 1) \\ = {2}^{4} \times 2 \\ = {2}^{4 + 1} \\ = {2}^{5} [/tex]
[tex]c = 4 \sqrt{36} \div 3 \times {2}^{2} \\ = 4 \times 6 \div 3 \times {2}^{2} \\ = 4 \times 2 \times {2}^{2} \\ = {2}^{2} \times 2 \times {2}^{2} \\ = {2}^{2 + 1 + 2} \\ = {2}^{5} \\ [/tex]
Et voilà j'espère t'avoir aidé bonne journée
