- ------------
√18x

yes it is a negative

Answer 1

let's do the same here.


`\bf -\cfrac{1}{√(18x)}\cdot \cfrac{√(18x)}{√(18x)}\implies -\cfrac{√(18x)}{√((18x)^2)}\implies -\cfrac{√(18x)}{18x}\implies -\cfrac{√(9\cdot 2\cdot x)}{18x} \\\\\\ -\cfrac{√(3^2\cdot 2\cdot x)}{18x}\implies -\cfrac{3√( 2\cdot x)}{18x}\implies -\cfrac{√(2x)}{6x}`
