Based on one of the laws of exponents, particularly the Power of Powers Rule states that when an exponent is powered by another exponent, we simply multiply them.
[tex](x^m)^n=x^{m\times n}[/tex]
So, for the c¹¹ being powered by the exponent 1/11, we will simply multiply 11 and 1/11.
[tex]c^{11\times\frac{1}{11}}\Rightarrow c^{\frac{11}{11}}\Rightarrow c^1\Rightarrow c[/tex]
Therefore, c¹¹ being powered by the exponent 1/11 is just equal to c.
