kak bantu pakek caranya

^ pangkat
1) x√x dx = x^1.x^½ dx
= x^(1+½) dx
= x^3/2 dx
= (1 / (3/2+1)) x^(3/2+1) + C
= (1 / (5/2)) x^(5/2) + C
= (2/5)x^5/2 + C
= (2/5)x²√x + C

2) integralin (3x² + 4x - 5) dx
x³ + 2x² - 5x + C
(x,y) = (1,2)
(1)³ + 2(1)² - 5(1) + C = 2
1 + 2 - 5 + C = 2
-2 + C = 2
C = 2 + 2 = 4
persamaan nya
y = x³ + 2x² - 5x + 4

3) interval 2 dan 0 2x(8-x²) dx
jabarin dulu kalikan 2x ke dalam kurung
(16x - 2x³) dx
= 8x² - ½x⁴
masukan interval
= {8(2)² - ½(2⁴)} - {8(0)² - ½(0⁴)}
= {32 - 8} - {0}
= 24

itu ajah bisanya
