Given:


7^{-(5)/(6)}\cdot7^{-(7)/(6)}

Required: To simplify the given expression.

This is explained thus:

Using the multiplication law and the negative index law of indices, we have:


\begin{gathered} 7^{-(5)/(6)}\cdot7^{-(7)/(6)} \\ =7^{-(5)/(6)+(-(7)/(6))} \\ =7^{-(5)/(6)-(7)/(6)} \\ =7^(-2) \\ =(1)/(7^2) \\ =(1)/(49) \end{gathered}

Hence, the answer is:


(1)/(49)
