Question

me ayudan operación con notación científica si no saben no respondan​

Answer 1

Respuesta:

$3) \: 3.26 \times {10}^{8}$

$4) \: 0.06 \times {10}^{2}$

Explicación paso a paso:

3)

$\frac{(1.2 \times {10}^{5} + 0.75 \times {10}^{5})7.2 \times {10}^{5} }{4.3 \times {10}^{2} }$

$\frac{(1.2 + 75) {10}^{5} \times 7.2 \times {10}^{5} }{4.3 \times {10}^{2} }$

$\frac{1.95 \times 7.2 \times {10}^{10}}{4.3 \times {10}^{2} }$

$\frac{14.04 \times {10}^{10}}{4.3 \times {10}^{2} }$

$\frac{14.04 \times {10}^{10 - 2} }{4. 3}</p><p> = \frac{14.04 \times {10}^{8} }{4.3} = 3.26 \times {10}^{8}$

4)

$\frac{(1.1 \times {10}^{5} - 0.899 \times {10}^{5}) + 2.3 \times {10}^{3} }{3.2 \times {10}^{3} }$

$\frac{(0.20 \times {10}^{5}) +2.3 \times {10}^{3} }{3.2 \times {10}^{3} }$

$\frac{0.20 \times {10}^{5} + 0.023 \times {10}^{5} }{3.2 \times {10}^{3} }$

$\frac{(0.20 + 0.023) {10}^{5} }{3.2 \times {10}^{3} }$

$\frac{0.223 \times {10}^{5} }{3.2 \times {10}^{3} }$

$\frac{0.223 \times {10}^{5 - 3} }{3.2} = 0.06 \times {10}^{2}$
