Question

?♧alguien please ? es para esta semana y boy a morir si no lo ago

Answer 1

Explicación paso a paso:

1.

${({c}^{4} \times {c}^{3} ) }^{6} \div {c}^{14} \\ \\ = {( {c}^{4 + 3}) }^{6} \div {c}^{14} \\\\ = {( {c}^{7}) }^{6} \div {c}^{14} \\\\ = {c}^{7 \times 6} \div {c}^{7 \times 2} \\\\ = {({c}^{7}})^{6 - 2} \\\\ = {({c}^{7}})^{4} \\\\ = {c}^{7 \times 4} \\\\ = {c}^{28}$

2.

${( {a}^{3} \div {a}^{2}) }^{4} \div {( {a}^{2}) }^{3} \\ \\ = {({a}^{3 - 2}) }^{4} \div {a}^{2 \times 3} \\ \\ = {({a}^{1}) }^{4} \div {a}^{6} \\ \\ = {a}^{4} \div {a}^{6} \\ \\ = {a}^{4 - 6} = {a}^{ - 2} = \frac{1}{ {a}^{2} }$

Como no se ven las alternativas, escribí algunas opciones de fracciones equivalentes:

3. 0,2= 2/10 = ⅕ = ³/15 = ...

4. 1,1 = 1⅒ = 11/10 = ...

5. 0,03 = 0,3/10 = 3/100 = 30/1000 =....

6. 2,25 = 22,5/10 = 225/100 = 45/20 = 9/4 = ...

7. 1,52 = 15,2/10 = 152/100 = 76/50 = 38/25 = ...

8. 2,45 = 24,5/10 = 245/100 = 49/20 = ...

9.

$(0.1 - 0.3 + 0.5) \times ( - \frac{12}{5} ) \\ \\ = (-0.1) \times ( - \frac{12}{5} ) \\ \\ = - \frac{1}{10} \times ( - \frac{12}{5} ) \\ \\ = \frac{12}{50} \\ \\ = \frac{6}{25} = 0.24$

Espero haberte ayudado.

¡ÉXITOS!
