Calculate

(1.6x10^3)+(4.58x10^4)
Write your answer in scientific notation.

To calculate the sum, we need to align the decimal points and add the numbers:

1.6x10^3
+ 4.58x10^4
_________

Next, we need to adjust the decimal point so that there is only one number to the left of it:

0.016x10^4
+ 4.58x10^4
_________

Finally, we can add the numbers together:

4.596x10^4

Therefore, the sum of (1.6x10^3) + (4.58x10^4) in scientific notation is 4.596x10^4.
