The sum written in standard index form is 1.13*10^6
How to add numbers in scientific notation?
So here we want to add two numbers that are written in scientific notation, these are:
(7.3*10^5) + (4*10^5)
Now we can take the factor "10^5" as a common factor, so we can write:
(7.3*10^5) + (4*10^5) = (7.3 + 4)*10^5 = 11.3*10^5
Now we want to write this in standard index form (this is scientific notation), so we can have only one decimal on the left side of the decimal point, then we can write this as:
11.3*10^5 = 1.13*10^6
