Respuesta:

[tex]3) \: 3.26 \times {10}^{8} [/tex]

[tex]4) \: 0.06 \times {10}^{2} [/tex]

Explicación paso a paso:

3)

[tex]\frac{(1.2 \times {10}^{5} + 0.75 \times {10}^{5})7.2 \times {10}^{5} }{4.3 \times {10}^{2} }[/tex]

[tex]\frac{(1.2 + 75) {10}^{5} \times 7.2 \times {10}^{5} }{4.3 \times {10}^{2} } [/tex]

[tex]\frac{1.95 \times 7.2 \times {10}^{10}}{4.3 \times {10}^{2} }[/tex]

[tex]\frac{14.04 \times {10}^{10}}{4.3 \times {10}^{2} }[/tex]

[tex]\frac{14.04 \times {10}^{10 - 2} }{4. 3}

= \frac{14.04 \times {10}^{8} }{4.3} = 3.26 \times {10}^{8}[/tex]

4)

[tex] \frac{(1.1 \times {10}^{5} - 0.899 \times {10}^{5}) + 2.3 \times {10}^{3} }{3.2 \times {10}^{3} } [/tex]

[tex] \frac{(0.20 \times {10}^{5}) +2.3 \times {10}^{3} }{3.2 \times {10}^{3} } [/tex]

[tex] \frac{0.20 \times {10}^{5} + 0.023 \times {10}^{5} }{3.2 \times {10}^{3} } [/tex]

[tex] \frac{(0.20 + 0.023) {10}^{5} }{3.2 \times {10}^{3} } [/tex]

[tex] \frac{0.223 \times {10}^{5} }{3.2 \times {10}^{3} } [/tex]

[tex] \frac{0.223 \times {10}^{5 - 3} }{3.2} = 0.06 \times {10}^{2} [/tex]
