To subtract numbers in scientific notation, we have to bring both to same powers of 10.

Let's change the first number to 10 to the power 8.

So, it will become:


2.53*10^5=0.00253*10^8

So, we have to perform:


1.3*10^8-0.00253*10^8

Now we simply perform the subtraction and tag along 10 to the power 8.

So,

1.3 - 0.00253 = 1.29747

So, answer is:


1.29747*10^8
