Rationalize:

square root of (5+h) minus square root of 5

divided by

h
 


We rationalize this numerator using its conjugate.

Multiply the top and bottom of the given ratio by sqrt(5 + h) + sqrt(5).

Simplify the top first because there will be a cancellation with the h on bottom.

 


Yes.

Using a keyboard, we type it this way:

1/[sqrt(5 + h) + sqrt(5)]
