2^2+3^2=c^2. 4+9=13

Question

And the answer is square root is 13  and it can't be reduce so it will be 3.61

Answer 1

 

2² + 3² = c²

 

4 + 9 = c²

 

13 = c²

 

c = √13 or (13)^1/2 = 3.6

 

 

Looks good.  3.6² = 13

 

I don't know what "algebraic form" is either.

 

 What was your question?

 

 

 

Answer 2

 You are correct, but why don't you write in algebraic form.
