Taking into account the scientific notation, the result of the sum is 6.6365×10⁵.
First, remember that scientific notation is a quick way to represent a number using powers of base ten.
The numbers are written as a product:
a×10ⁿ
where:
You want to add two numbers in scientific notation. It should be noted that when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found.
In this case, the highest exponent is 5.
Then all the values are expressed as a function of the base 10 exponent with the highest exponent. In this case: 8.6500×10³= 0.086500×10⁵
Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:
0.086500×10⁵ + 6.5500×10⁵= (0.086500+ 6.5500)×10⁵= 6.6365×10⁵
Finally, the result of the sum is 6.6365×10⁵.
