The equivalent to the quotient shown in the task content for acceptable values of x is; √(5/(x-1)).
<h3>What is the equivalent of the quotient?</h3>
It follows from the task content that the expression given is; √(25(x-1)) ÷ √(5(x-1)²).
It therefore follows from the the laws of indices that the evaluation is thus;
= √{(25/5) ×(x-1)/(x-1)²}.
Ultimately, upon evaluation we have;
= √(5/(x-1))
