Add. Write your answer in scientific notation. (4.04 × 10^8) + (7 × 10^9)

To add the numbers in scientific notation, we need them to be expressed with the same exponent.

1. Convert ( 7 × 10^9 ) to the same exponent as ( 4.04 × 10^8 ):

– ( 7 × 10^9 = 70 × 10^8 ) (since ( 10^9 = 10 × 10^8 ))

2. Now, we can add them together:

[

(4.04 × 10^8) + (70 × 10^8) = (4.04 + 70) × 10^8 = 74.04 × 10^8

]

3. Convert ( 74.04 × 10^8 ) to proper scientific notation:

– Move the decimal one place to the left, which increases the exponent by 1:

[

7.404 × 10^9

]

So, the final answer is ( 7.404 × 10^9 ).
