    First, please don't post the same question repeatedly!

    Second, this looks like homework and should be in the homework section.

    Finally, since A= 3.25+/- 0.05, the largest it can be is 3.25+ 0.05= 3.30 and the smallest it can be is 3.25- 0.05= 3.20. Similarly, largest B can be is 2.06 and the smallest is 2.04. What are the largest and smallest that [itex]\sqrt{A^2+ B^2}[/itex] can be?
