  • Câu hỏi:

    Tìm nguyên hàm của hàm số \(f\left( x \right) = {e^{\frac{1}{2}x}}.\)

    • A. \(\int {f\left( x \right)d{\rm{x}}}  = 2{e^{\frac{1}{2}x}} + C.\)
    • B. \(\int {f\left( x \right)d{\rm{x}}}  = \frac{1}{2}{e^{\frac{1}{2}x}} + C.\)
    • C. \(\int {f\left( x \right)d{\rm{x}}}  = {e^{\frac{1}{2}x}} + C.\)
    • D. \(\int {f\left( x \right)d{\rm{x}}}  = \frac{2}{3}{e^{\frac{1}{2}x}} + C.\)

    Đáp án đúng: A

    Ta có: \(\int {f\left( x \right)d{\rm{x}}}  = \int {{e^{\frac{1}{2}x}}d{\rm{x}}}  = 2{{\rm{e}}^{\frac{1}{2}x}} + C.\)
