Answer:

2.[tex]7.589\times10^{11}[/tex]

Step-by-step explanation:

In order to find the answer to this question convert all notations into standard form and then multiply.

1.

[tex]7.0 \times10^3\times7.0\times10^3[/tex]

[tex]7.0.0.0.=7000[/tex]

[tex]7000\times7000=49000000[/tex]

Convert back into notation:

[tex]49000000 = 4.9\times10^7[/tex]

2.

[tex]8.7\times10^5\times8.7\times10^5[/tex]

[tex]8.7 = 8.7.0.0.0.0. = 870000[/tex]

[tex]870000 \times 870000 = 756900000000[/tex]

Convert back into notation:

[tex]756900000000=7.589\times10^{11}[/tex]

[tex]7.589\times10^{11}[/tex]

Hope this helps.
