lim_{x->0^{+}}(1+sinx)^{\frac{1}{\sqrt{x}}}



i get here 1^{\infty} form which states that's its some sort of exponent

Use "[ tex]" with no space in front of the 't' and "[ /tex]" with no space in front of the '/'. Capital letters do not work.

Use the identity 1+sin(x)=e^{ln(1+sin(x))}.

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
