Para resolver cada uno de estos cálculos, vamos a seguir paso a paso, simplificando las expresiones y utilizando las propiedades de las potencias.

a) (4,22108)+(3,4107)2105\frac{\left(4,22 \cdot 10^{8}\right)+\left(3,4 \cdot 10^{7}\right)}{2 \cdot 10^{5}}

Primero, sumamos los numeradores:

4,22108+3,4107=4,22108+0,34108=(4,22+0,34)108=4,56108 4,22 \cdot 10^{8} + 3,4 \cdot 10^{7} = 4,22 \cdot 10^{8} + 0,34 \cdot 10^{8} = (4,22 + 0,34) \cdot 10^{8} = 4,56 \cdot 10^{8}

Luego, dividimos por el denominador:

4,561082105=4,562108105=2,28103 \frac{4,56 \cdot 10^{8}}{2 \cdot 10^{5}} = \frac{4,56}{2} \cdot \frac{10^{8}}{10^{5}} = 2,28 \cdot 10^{3}

c) 4,22107(8,86106)(4,2105)\frac{4,22 \cdot 10^{7}}{\left(8,86 \cdot 10^{6}\right)-\left(4,2 \cdot 10^{5}\right)}

Primero, restamos en el denominador:

8,861064,2105=8,861060,42106=(8,860,42)106=8,44106 8,86 \cdot 10^{6} - 4,2 \cdot 10^{5} = 8,86 \cdot 10^{6} - 0,42 \cdot 10^{6} = (8,86 - 0,42) \cdot 10^{6} = 8,44 \cdot 10^{6}

Luego, dividimos:

4,221078,44106=4,228,44107106=0,5101=5 \frac{4,22 \cdot 10^{7}}{8,44 \cdot 10^{6}} = \frac{4,22}{8,44} \cdot \frac{10^{7}}{10^{6}} = 0,5 \cdot 10^{1} = 5

b) (9,41012)(1,51013)61026\frac{\left(9,4 \cdot 10^{12}\right) \cdot\left(1,5 \cdot 10^{13}\right)}{6 \cdot 10^{26}}

Multiplicamos primero los numeradores:

9,410121,51013=(9,41,5)(10121013)=14,11025 9,4 \cdot 10^{12} \cdot 1,5 \cdot 10^{13} = (9,4 \cdot 1,5) \cdot (10^{12} \cdot 10^{13}) = 14,1 \cdot 10^{25}

Ahora dividimos por el denominador:

14,1102561026=14,1610251026=2,35101 \frac{14,1 \cdot 10^{25}}{6 \cdot 10^{26}} = \frac{14,1}{6} \cdot \frac{10^{25}}{10^{26}} = 2,35 \cdot 10^{-1}

Por lo tanto, los resultados son:

a) 2,281032,28 \cdot 10^{3}

c) 55

b) 2,351012,35 \cdot 10^{-1}
