Sagot :

Vamos a resolver la expresión paso a paso:

[tex]\[3^4 - 18 \div \sqrt{9} \times 7 + 8^0 \times 20 \div 5\][/tex]

1. Primero, evaluamos [tex]\(3^4\)[/tex]:
[tex]\[3^4 = 81\][/tex]

2. Luego, calculamos [tex]\(\sqrt{9}\)[/tex]:
[tex]\[\sqrt{9} = 3\][/tex]

3. A continuación, dividimos 18 entre [tex]\(\sqrt{9}\)[/tex]:
[tex]\[18 \div 3 = 6\][/tex]

4. Multiplicamos el resultado por 7:
[tex]\[6 \times 7 = 42\][/tex]

5. Ahora evaluamos [tex]\(8^0\)[/tex]:
[tex]\[8^0 = 1\][/tex]

6. Multiplicamos este resultado por 20:
[tex]\[1 \times 20 = 20\][/tex]

7. Finalmente, dividimos este resultado por 5:
[tex]\[20 \div 5 = 4\][/tex]

Ahora combinamos todos los resultados anteriores en la expresión original:

[tex]\[81 - 42 + 4\][/tex]

Realizamos las operaciones secuenciales:
[tex]\[81 - 42 = 39\][/tex]
[tex]\[39 + 4 = 43\][/tex]

Por lo tanto, el valor de la expresión es [tex]\(43\)[/tex].

La respuesta correcta es [tex]\( \boxed{43} \)[/tex].
