SOLUTION: This is correct: c^2=a^2+b^2 c^2=1^2+1^2 c^2=1+1 c^2=2 c=squrt2 c=1.414

Algebra ->  Pythagorean-theorem -> SOLUTION: This is correct: c^2=a^2+b^2 c^2=1^2+1^2 c^2=1+1 c^2=2 c=squrt2 c=1.414       Log On


   

Question 548430: This is correct:
c^2=a^2+b^2
c^2=1^2+1^2
c^2=1+1
c^2=2
c=squrt2
c=1.414

Why is this wrong?
c^2=a^2+b^2
c^2=1^2+1^2
c^2=2^2 Added similar terms: same base no.1;and exponent no,2.
c^2=squrt 2^2
c=2 which is not 1.414
