6598
We know that
By taking square root
81² is less than 6598
So by taking 82²
324−198=126 less
Adding 126 we get a square of 82 which is 6724.

AB²=98
AC=BC. (since it is an isosceles triangle, two sides are equal)

by Pythagoras theorem,

AB² = AC² + BC²

we know AC = BC,

therefore substitute

AB² = AC² + AC²

98 = 2AC²

98/2 = AC²

49 = AC²

therefore,. AC = √49

AC = 7

AC = BC = 7
