Math Help please! :)

I need some help with a problem for Pythagorean Theorem, if you would like to help!

13.65=√6.5^2+12^2
For the problem above, I need help finding the steps to doing it, I'm one of those kinds of people that can get the problem, but not sure how I got it.

√4^2+9^2
For the problem above, I'm confused and am unsure how to get the answer.

Thanks :)

  2. The square root of a squared value is that value.

    e.g., √4^2+9^2 = 4 + 81 = ?

  3. I think you wanted
    √(4^2 + 9^2) = √(16+81) = √97
    But you did not include the parentheses, so PsyDAG's result is correct for what you posted.
    √(6.5^2 + 12^2) = √(42.25 + 144) = √186.25 = 13.65
