Answer» given √n(n+2) = 4.1=> n(n+2) = (41/10)²=> n²+2n -1681/100 = 0=> 100n²+200n-1681 = 0 n =( -b±√D/2a ) , a = 100, b = 200, c = -1681 so, n = 3.220189569201839 , -5.220189569201839 √n(n+2) = 2.9=> n(n+2) = (29/10)²=> n²+2n -841/100 = 0=> 100n²+200n-841= 0 n =( -b±√D/2a ) , a = 100, b = 200, c = -841 so, n = 2.067572330, -4.06757233

Answer»

given √n(n+2) = 4.1=> n(n+2) = (41/10)²=> n²+2n -1681/100 = 0=> 100n²+200n-1681 = 0 n =( -b±√D/2a ) , a = 100, b = 200, c = -1681

so, n = 3.220189569201839 , -5.220189569201839

√n(n+2) = 2.9=> n(n+2) = (29/10)²=> n²+2n -841/100 = 0=> 100n²+200n-841= 0 n =( -b±√D/2a ) , a = 100, b = 200, c = -841

so, n = 2.067572330, -4.06757233
