Answer:
796
Step-by-step explanation:
We have given the number 756, 37.2, 0.83, 2
We have to find the sum of the number to the correct number of significant figure
So the sum 756+37.2+0.83+2=796.03
As the maximum significant figure is 3 in the given numbers
So we have to write the answer up to three significant figure
So answer will be 796
