Perform the following operation and express the answer in scientific notation 8.6500x10^3+6.5500x10^5
Dafna1 [17]

Taking into account the scientific notation, the result of the sum is 6.6365×10⁵.

<h3>Scientific notation</h3>

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:

  • a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.
  • n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.

<h3>Sum in scientific notation</h3>

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=  <u><em>6.6365×10⁵</em></u>

Finally, the result of the sum is 6.6365×10⁵.
