The proper value of significant figures in $$38.0+ 0.0035 + 0.00003$$ is: 


ANSWER

38.0


SOLUTION
The value of the sum   $$38.0+0.0035+0.00003 = 38.00353$$
Since the digit has  $$38.0$$ has only  $$1$$ significant figure after the decimal, so the final answer must also have $$1$$ significant figure after the decimal.
So, the proper value of the sum is  $$38.0$$
