Explicación paso a paso:

a)

$2^3\cdot \:3+4^2\div \:8-5^2\\\\\\8\cdot \:3+4^2\div \:8-5^2\\\\\\8\cdot \:3+16\div \:8-5^2\\\\\\8\cdot \:3+16\div \:8-25\\\\\\24+16\div \:8-25\\\\\\24+2-25\\\\\\1$

b)

$2\left(4-1\right)^2+18\div \left(2^3+2^0\right)\\\\\\2\cdot \:3^2+18\div \left(2^3+2^0\right)\\\\\\2\cdot \:3^2+18\div \:9\\\\\\2\cdot \:9+18\div \:9\\\\\\18+18\div \:9\\\\\\18+2\\\\\\20$

c)

$2\cdot \:11^2-6^3-5\sqrt[3]{125}+8^0\\\\\\11^2\cdot \:2-6^3-5\sqrt[3]{125}+1\\\\\\11^2\cdot \:2-6^3-25+1\\\\\\11^2\cdot \:2-6^3-24\\\\\\242-216-24\\\\\\2$

d)

$\frac{\left(1+2\right)^3}{\sqrt{9}-\sqrt{8+2^3}}\\\\\\\frac{3^3}{\sqrt{9}-\sqrt{2^3+8}}\\\\\\\frac{3^3}{\sqrt{9}-\sqrt{16}}\\\\\\\frac{3^3}{3-4}\\\\\\\frac{3^3}{-1}\\\\\\-\frac{3^3}{1}\\\\\\-3^3\\\\\\-27$

Answer 2

Respuesta:

Hola

Explicación paso a paso:

a=2(al cubo) * 3+2(a la cuatro): 2(al cubo) - 5(al cuad)

2*3(1+2x3) : 2*3 -5*2

2*3(7) : 2*3 (se van el 2*3) -5*2

7-25=-18

b=20

c=242-216-30

c=-4

d=9-4=5

espero te sirva
