Answer:
[tex]5.86*10^{5}[/tex]
Explanation:
first you change the smaller number so that the 10 on both of them is power to the same number.
3.8*10^4
here we will change this number so that it is 10^5 which mean will move the decimal point one digit to the left.
0.38*10^5
now we will add the two numbers while keeping the 10^5.
5.3*10^5 + 0.38*10^5 = 5.68*10^5
