(2x10^5) + (6x10^5) In Scientific Notation

Adding Numbers in Scientific Notation: (2 x 10^5) + (6 x 10^5)

Let's explore how to add numbers expressed in scientific notation.

Understanding Scientific Notation

Scientific notation is a convenient way to express very large or very small numbers. It follows the form:

a x 10^b

Where:

  • a is a number between 1 and 10 (but not including 10)
  • b is an integer representing the power of 10.

Adding Numbers in Scientific Notation

To add numbers in scientific notation, they must have the same exponent (same power of 10).

Step 1: Check the Exponents

In our case, both numbers have the same exponent (10^5).

Step 2: Add the Coefficients

Add the coefficients (the numbers in front of the power of 10):

2 + 6 = 8

Step 3: Express the Result in Scientific Notation

Combine the result with the common exponent:

8 x 10^5

Therefore, (2 x 10^5) + (6 x 10^5) = 8 x 10^5
