Question

Need help with simplifying fractional expression. please.

Answer 1

\[\frac{ \frac{ 1 }{ \sqrt{x+h}}-\frac{ 1 }{ \sqrt{x} } }{ h}\]

Answer 2

did you try to subtract the two fractions (use a common denominator)
as a first step

Answer 3

combine the top first.
\[\frac{ \frac{ 1 }{ \sqrt{x+h} } -\frac{ 1 }{ \sqrt{z} }}{ h}\]
\[\frac{\frac{\sqrt{z}}{\sqrt{x+h}}-\frac{\sqrt{x+h}}{\sqrt{z}}}{h}\]
\[\frac{\frac{\sqrt{z}-\sqrt{x+h}}{\sqrt{z}\sqrt{x+h}}}{h}\]
\[\frac{\sqrt{z}-\sqrt{x+h}}{h*\sqrt{z}*\sqrt{x+h}}\]
