Answer:
sum = [tex]2.85*10^3[/tex]
Step-by-step explanation:
Given are two numbers in scientific notation and we have to add them
The numbers are
[tex]1) 2.5*10^3\\ 2) 3.5*10^2[/tex]
As such we cannot add as these are numbers not like terms.
We can either make both with same powers of x and add.
[tex]1) 2.5*10^3\\\\ 2) 3.5x10^2=0.35*10^3[/tex]
Now we can add since both are like terms.
Adding we get
sum = [tex]2.85*10^3[/tex]
