In δabc, ac = bc side cd is the median of side ab with d belonging to side ab, ab = 4 in and cd = sqaure root of 3 in. find ac.

AC = √7 in

Step-by-step explanation:

ΔABC is isosceles, so ΔADC is a right triangle with AD = 2 in and CD = √3 in. The length of hypotenuse AC is found using the Pythagorean theorem.

... AC² = AD² +CD² = (2 in)² +(√3 in)² = (4 +3) in²

... AC = √7 in . . . . take the square root

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
