Answer :
We start with the two numbers in scientific notation:
[tex]$$
5.78 \times 10^5 \quad \text{and} \quad 1.69 \times 10^5.
$$[/tex]
Since the powers of 10 are the same, we can add the coefficients directly:
[tex]$$
5.78 + 1.69 = 7.47.
$$[/tex]
Therefore, the sum is:
[tex]$$
7.47 \times 10^5.
$$[/tex]
Thus, the answer in scientific notation is [tex]$$7.47 \times 10^5.$$[/tex]
