Simplify the radical expression so that it can be written as kh^rs^t ∛125h^2s^9 ÷ ∛h^1s^4

where r, the exponent of h is-
where t, the exponent of s is-
where k, the leading coefficent is-

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
