(6.31 x10^5) + (2.6x10^4)

= (63.1 x10^4) + (2.6x10^4)

= 10^4(63.1 + 2.6)

= 65.7 x 10^4

= 6.57 x 10^5

The sum of the given scientific notations is [tex]6.57\times 10^5[/tex]

Given the sum of the scientific notations:

[tex](6.31 x10^5) + (2.6x10^4)[/tex]

Convert both to integers as shown:

[tex]6.31 \times 10^5 = 631000[/tex]

[tex]2.6 \times 10^4 = 26000[/tex]

Taking the sum of the integers

[tex]631000 + 26000 = 657,000[/tex]

Express the result in scientific notations:

[tex]657,000 = 6.57 \times 10^5[/tex]

Hence the sum of the given scientific notations is [tex]6.57\times 10^5[/tex]
