Your answer is 693.1.
Remove unneeded parentheses from both equations.
That will give us the following...
1.2 x 105 + 5.35 x 106
So now lets solve 1.2 x 105.
1.2 x 105=126
Next, lets solve 5.35 x 106.
5.35 x 106= 567.1
Finally, we add the two together!
126+567.1=693.1
Up above is your final answer!
