To rationalize the denominator and simplify the expression sqrt(10)/(sqrt(5)-2), we can multiply both the numerator and denominator by the conjugate of the denominator, which is sqrt(5)+2. This will eliminate the square root in the denominator.

By applying the conjugate, we get: (sqrt(10)/(sqrt(5)-2)) * ((sqrt(5)+2)/(sqrt(5)+2))

Simplifying this expression, we have:
(sqrt(10)*(sqrt(5)+2))/((sqrt(5)-2)*(sqrt(5)+2))

Expanding the denominator using the difference of squares, we get: (sqrt(10)*(sqrt(5)+2))/(5-4)

Further simplifying, we have: (sqrt(10)*(sqrt(5)+2))/1

Finally, we can simplify the expression to: sqrt(10)*(sqrt(5)+2)
