Answer:
(49) ki power 5/2 - (49)ki power 7/2 / (49) ki power 7/2
=(7) ki power 2*5/2 - (7) ki power 2*7/2 / (7) ki power 2*7/2
=7 ki power 5 - 7 ki power 7 / 7 ki power 7
= [ 7 ki power 5 / 7 ki power 7] - [ 7 ki power 7 / 7 ki power 7 ]
= [ 7 ki power 5-7 ] - [ 7 ki power 7-7 ]
= [ 7 ki power -2 ] - [ 7 ki power 0 ]
= [ 1/7 ki power 2 ] -1
= 1 / 49 -1
= 1 - 49 / 49
