Tolong jawaban dan cara nya ya kakak nmr 26 dan 27

tanda ^ pangkat
26.
2 / x^1.x^1/2
2 / x^(1+1/2)
2 / x^3/2
2 x^-3/2 dx
integral kan
2(1 / (-3/2 + 1)) x^(-3/2+1)
2(1 / (-1/2)) x^-1/2
2(-2) x^-1/2
-4 / √x
masukan interval 4 dan 1
-4/√4 - {-4/√1}
-4/2 - {-4/1}
-2 + 4
2

27.
y = x²
x + y = 6
y = 6 - x
x² = 6 - x
x² + x - 6 = 0
(x + 3)(x - 2) = 0
x = -3 dan x = 2
6 - x - x² dx
6x - 1/2x² - 1/3x³
masukan interval x = 2 dan -3
6(2)-1/2(2)²-1/3(2)³ - {6(-3)-1/2(-3)²-1/3(-3)³}
12 - 2 - 8/3 - {-18 - 9/2 + 9}
10 - 8/3 - {-9 - 9/2}
19 - 8/3 + 9 + 9/2
19 - 8/3 + 9/2
114/6 - 16/6 + 27/6
125/6
= 20(5/6)
