The value of the addition operation is 2.38157 x 10^19
<h3>How to add the numbers/expressions?</h3>
The numbers are given as:
2.35 x 10^19 and 3.157 x 10^17.
Express as sum
2.35 x 10^19 + 3.157 x 10^17.
Express 10^17 as 10^19 * 10^-2
So, we have:
2.35 x 10^19 + 3.157 x 10^19 * 10^-2
Factor out 10^19
(2.35 + 3.157 * 10^-2) x 10^19
Express 10^-2 as 0.01
(2.35 + 3.157 * 0.01) x 10^19
This gives
(2.35 + 0.03157) x 10^19
Evaluate the sum
2.38157 x 10^19
Hence, the value of the addition operation is 2.38157 x 10^19
