The problem asks us to add two numbers in scientific notation, $(4.36 \times 10^5) + (3.75 \times 10^5)$, and express the result in scientific notation.

1. Problem Description

The problem asks us to add two numbers in scientific notation, $(4.36 \times 10^5) + (3.75 \times 10^5)$, and express the result in scientific notation.

2. Solution Steps

Since both numbers have the same power of 10, we can simply add the coefficients:

$4.36 + 3.75 = 8.11$

Then, we multiply the result by the common power of 10:

$8.11 \times 10^5$

The number is already in scientific notation since the coefficient, 8.11, is between 1 and

1

0.

3. Final Answer

$8.11$
