Answer 1

Respuesta:

$a)7.12 \times {10}^{12} +6.7 \times {10}^{11} = 7.12 \times 10 \times {10}^{11} + 6.7 \times {10}^{11} = 71.2 \times {10}^{11} + 6.7 \times {10}^{11} = (71.2 + 6.7) \times {10}^{11} = 77.9 \times {10}^{11}$

$b)8.3 \times {10}^{8} - 3.1 \times {10}^{7} = 8.3 \times 10 \times {10}^{7} - 3.1 \times {10}^{7} = 83 \times {10}^{7} - 3.1 \times {10}^{7} = (83 - 3.1) \times {10}^{7} = 79.9 \times {10}^{7}$

$c) \frac{5.2 \times {10}^{9} }{2.6 \times {10}^{7} } + 1.7 \times {10}^{3} = (5.2 \div 2.6) \times ( {10}^{9} \div {10}^{7} ) + 1.7 \times {10}^{3} = 2 \times {10}^{2} + 1.7 \times {10}^{3} = 2 \times {10}^{2} + 1.7 \times 10 \times {10}^{2} = 2 \times {10}^{2} + 17 \times {10}^{2} = (2 + 17) \times {10}^{2} = 19 \times {10}^{2}$
