= (36 to power 7/2 - 36 to power 9/2) /36 to power 5/2
= (6 to power 7 - 6 to power 9) /6 to power 5
= (6×6×6×6×6×6×6 - 6×6×6×6×6×6×6×6×6) /6×6×6×6×6
=6×6×6×6×6×6×6(1-6×6) /6×6×6×6×6
=(36 - 1296)
= 1260
= (6 to power 7 - 6 to power 9) /6 to power 5
= (6×6×6×6×6×6×6 - 6×6×6×6×6×6×6×6×6) /6×6×6×6×6
=6×6×6×6×6×6×6(1-6×6) /6×6×6×6×6
=(36 - 1296)
= 1260
