Integral(5^(2*x), (x, 0, 1))
Detail solution
  1. Let u=2xu = 2 x.

    Then let du=2dxdu = 2 dx and substitute du2\frac{du}{2}:

    5u2du\int \frac{5^{u}}{2}\, du

    1. The integral of a constant times a function is the constant times the integral of the function:

      5udu=5udu2\int 5^{u}\, du = \frac{\int 5^{u}\, du}{2}

      1. The integral of an exponential function is itself divided by the natural logarithm of the base.

        5udu=5ulog(5)\int 5^{u}\, du = \frac{5^{u}}{\log{\left(5 \right)}}

      So, the result is: 5u2log(5)\frac{5^{u}}{2 \log{\left(5 \right)}}

    Now substitute uu back in:

    52x2log(5)\frac{5^{2 x}}{2 \log{\left(5 \right)}}

  2. Now simplify:

    25x2log(5)\frac{25^{x}}{2 \log{\left(5 \right)}}

  3. Add the constant of integration:

    25x2log(5)+constant\frac{25^{x}}{2 \log{\left(5 \right)}}+ \mathrm{constant}


The answer is:

25x2log(5)+constant\frac{25^{x}}{2 \log{\left(5 \right)}}+ \mathrm{constant}
