berikut.
a. 1 sampai 3 10/(2x + 3)^2 dx
b. 4 sampai 7 akar dari 3x+4 dx
dijawab plz
3. Hitunglah nilai setiap integral tertentu
integralTentu
–
₁³∫ 10(2x+ 3)⁻² dx
= -5 (2x+ 3)⁻¹ ]³₁
= – 5 (9^-1 - 5^-1)
= – 5 (1/9 – 1/5)
= -5 (- 4/45)
= 4/9
₄⁷∫ √(3x+ 4) dx = ₄⁷∫ (3x+ 4)^(1/2) dx
= 1/3. 2/3 (3x+ 4)^(3/2) ]⁷₄
= 2[ (3x + 4)^(3/2) ]⁷₄
= 2 (25^(3/2) – 16^(3/2)
= 2 (5^3 – 4^3 )
= 2 (125 – 64)
= 122
