mohon di jawab ya kak no 6 7 8

6.)Lim (x - 5)/akar(x^2 - 25) = Lim (x - 5)akar(x^2 - 25)/(x^2 - 25) = Lim (x - 5) akar(x^2 - 25)/(x + 5)(x - 5) = Lim akar(x^2 - 25)/(x + 5) = akar (25 -25)/(5 + 5) = 0/10 = 0

7.) Lim (x - 1)/akar(x^2 + 3) - 2 = Lim ((x - 1) × *akar(x^2 + 3) + 2))/((x^2 + 3) - 4) = Lim ((x - 1) × (akar(x^2 + 3) + 2))/(x^2 -1) = Lim akar(x^2 +3) +2 /(x + 1) = akar(1+3)/(1+1) = 2/2= 1

8.) Lim (1 - x^2)/(2 - akar(x^2 + 3)) = Lim (1 - x^2)(2 + akar(x^2 + 3))/(4 - (x^2 + 3)) = Lim 2 + akar(x^2 + 3) = 2 + akar(1 +3) =2 + 2 = 4
