1^ any real number = 1
So 1^x=1
The integral of 1 is x+c
I think that is the answer
integration of 1^x
$$\int{1^x}\ dx \ ?$$
$$\begin{array}{llr}
set & \quad 1^x=e^ { x \times \ln{(1)} } & \qquad \ln{(1)} = 0\\
so & \quad 1^x=e^ { x \times 0} & \qquad x\times0= 0\\
so & \quad 1^x=e^0 & \qquad e^0=1\\
so & \quad 1^x=1
\end{array} \\
\int{1^x}\ dx = \int{1}\ dx = x + c$$
